Preparation of Identification by Ir and Nmr Spectroscopy free essay sample

The reactive acid chloride can then be treated with a primary or secondary amine to give the amide along with HCl, which reacts with the excess amine to give an alkylammonium chloride salt. The mechanism of this process is shown on the following page in Scheme 22: [pic] Scheme 2 To carry out this reaction, the apparatus shown in Figure 1 will be assembled. The apparatus must be dry, since thionyl chloride will react with water to give sulfur dioxide and hydrogen chloride. The acid chloride will then be cooled to room temperature and dissolved in anhydrous ether. Ice-cold diethylamine will be added as a solution in anhydrous ether to form the amide. The resulting ether mixture will washed with aqueous sodium hydroxide (to remove any excess acid chloride), then washed with hydrochloric acid (to remove any excess diethylamine). The resulting ether solution of DEET will be dried and evaporated to yield the crude product, which will then be purified by column chromatography to afford pure DEET. We will write a custom essay sample on Preparation of Identification by Ir and Nmr Spectroscopy or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page The percent yield from m-toluic acid will be determined and the product will be analyzed by transmission infrared spectroscopy (IR) as a neat sample using NaCl plates5 to confirm its structure by (1) looking at the major absorptions and comparing them to a correlation table6 and (2) by comparing the spectrum to that of an authentic sample. Thionyl chloride is toxic and corrosive! Do not breath the vapors! Use in a hood! When heating a reaction apparatus, be sure that it is open to the air so that pressure build up and subsequent rupture of the apparatus does not occur. When heating liquids, make sure the liquid is stirred (or a boiling chip is added) to prevent â€Å"bumping†. When performing an extraction, make sure to vent the separatory funnel often to prevent pressure build-up. The apparatus shown in Figure 1 was assembled. The 10-mL reaction flask was charged with 0. 275 g of m-toluic acid (0. 0020 mol) and 0. 30 mL of thionyl chloride (0. 492 g, 0. 0041 mol). The condenser water was started, and the mixture was gently heated with stirring on an aluminum block (block temp ~ 90 oC) until boiling started. The reaction mixture was then gently boiled for about 15 minutes. After the boiling period was finished, the reaction mixture was cooled to room temperature. 4. 0 mL of anhydrous ether were added, and the mixture was stirred at room temperature until a homogeneous mixture was obtained. To this solution was added (dropwise over a 15 minute period) a solution of 0. 6 mL of cold (0 oC) diethylamine (0. 462 g, 0. 0063 mol) in 1. 33 mL of anhydrous ether. During the addition, a thick white cloud of diethylamine hydrochloride was formed. After complete addition, the reaction mixture was stirred at room temperature for about 10 minutes. 10% aqueous sodium hydroxide (2 mL) was then added, and the reaction mixture was stirred for an additional 15 minutes at room temperature, then poured into a separatory funnel and allowed to separate. The aqueous layer was discarded, and the organic layer was washed with an additional portion of 10% aqueous sodium hydroxide (2 mL), followed by a portion of 10% hydrochloric acid (2 mL). The organic layer was washed with water (2 mL), dried (Na2SO4) and evaporated to yield crude N,N-diethyl-m-toluamide as dark brown liquid. The crude product was filtered through a short alumina column using hexane as the eluent (~ 5 mL). The hexane solution was evaporated to give 0. 340 g of pure N,N-diethyl-m-toluamide as a yellow liquid. Reaction of m-toluic acid with thionyl chloride, followed by diethylamine produced 0. 340 g of a yellow liquid the IR spectrum of which unequivocally showed the presence of the amide carbonyl functional group at 1633 cm-1. In addition, absorptions due to aliphatic C-H (2980 – 2880 cm-1), and aromatic C=C (at 1585 cm-1). The IR spectrum is attached to this report. These data are consistent with the structure of N,N-diethyl-m-toluamide (DEET), shown in Figure 2 below: [pic] Figure 2: N,N-Diethyl-m-toluamide (DEET) In addition, the IR of the product closely corresponds with that of an authentic sample of N,N-diethyl-m-toluamide (DEET) shown in the lab text. 9 Also, the 1H-NMR shows the presence of four (4) aromatic protons in the region 7. 3 – 7. 1 ppm, as well as a three (3) proton singlet at 2. 35 ppm, which corresponds to the benzylic methyl group. The presence of two ethyl groups is clearly shown by the presence of two quartets which integrate to 2 protons each at 3. 53 and 3. 24 ppm, and two triplets which integrate to 3 protons each at 1. 23 and 1. 09 ppm.

What You Need To Know About Writing A Background Essay Sample

What You Need To Know About Writing A Background Essay SampleStudents in the US are expected to write a college essay, as part of their admission process. It is a part of the application to the college for which they are expected to write a speech or essay, in a short period of time.

This is not a paper just a MIDTERM question Essay - 1

This is not a paper just a MIDTERM question - Essay Example However, through the Bureau of budget formed in 1970 during President Nixon’s Administration which was and is still referred to as the Office of Management and Budget (OMB). This office is the largest office in the Executive office of the President, and is mandated to advise the president on issues related to budgeting and finance, also to countercheck and oversee budget and financial management of other executive branch groups (Gibbler, 2006, p. 14). In the congressional; action process, the budgeting committee through the Congressional act of 1974 direct s that the president submits the proposed budget to the House and Senate Budget committees so that the budget resolution may be created to serve as a universal framework through which the decisions of specific government spending and tax levies would be based upon. However, they do mot make budget nor do they require president’s signature but their mandate is to establish the budget structure to avoid both misappropriation and over estimation of the US Budget. The process is mandated to lay out guideline plan for government tax and disbursement in the next fiscal year. The Budget resolution is mandated to dictate the amount of money that ne government is permitted to pay out in the 20 Budget allocations. This process is controlled by the Committee on appropriation (Gibbler, 2006, p. 38). The process is mandated to take effect after the budget is through. Through the Appropriation Bill, the process should distribute funds to the key government programs through agencies to ensure that the prospective departments receive funding as appropriated in the budget (Gibbler, 2006, p. 72). Due to the poor economic state affecting the whole world, tax rates should be reviewed so tat the country and world businesses move.

Women in a patriarchal society and trifles Essay

Women in a patriarchal society and trifles - Essay Example The play Trifles revolves around the investigation conducted by a sheriff and a county attorney in the house of a woman who was accused of murdering her husband who was found in his bed with a rope around in his neck. Accompanying them is the couple’s neighbor who was the first man to discover the body. In the background, are wives of the sheriff and the neighbor who tagged along with their husbands while the men went around the house searching for evidence that would clearly show the motive of the wife in the killing of her husband. Glaspell’s play highlights the structural distinction between men and women in a patriarchal society in which women are regarded as inferior to men. Men, for example, hold significant jobs while women were kept in homes, cleaning, cooking, quilting and having babies. This inequality between the sexes places wives at a disadvantage because while men hold jobs keeping them out of the house most of the time and exposing them to a social life, women were tied down to their chores in homes with no one to share their thoughts with and no one to keep them company except husbands who come home at night and who did not treat them on equal footing. Minnie Wright exemplifies this type of a woman whose world had been confined to the four corners of her home, lonely and desperate and living with a husband who obviously kept to himself and who wanted to shut the noise out of their home. When he wrung the neck of her bird, her last source of joy, perhaps to keep it quiet forever, Mrs. Wrigh t finally snapped and tied a rope around his neck while he was asleep. All throughout the play, the same pattern of inequality between men and women are reflected by the other characters of the play with women playing secondary role to male characters. II In Trifles, Glaspell shows that men regarded women as beneath them and

Why the Legal Drinking Age Shouldnt be lowered Essay Example for Free

Why the Legal Drinking Age Shouldnt be lowered Essay In the United States, the legal drinking age for all fifty states and the District of Columbia is twenty-one. The drinking age is twenty-one because the government decided this is when a person becomes legally responsible to handle the repercussions of consuming alcohol. The U. S. has the highest legal drinking age in the world. Only four countries in the world have a legal drinking age over eighteen, making the US an exception rather than the rule. Some people may argue that the government should lower the drinking age since you legally become an adult at age eighteen, but I completely understand this law and am totally for it. Underage drinking has become an epidemic that has spread all over the world, but more so in the United States than any other country. This is disturbing because the brain is not fully developed until a person is around twenty-two years of age. Therefore, it should be harder for minors to obtain alcohol, and the legal drinking age should not be lowered. What is alcohol, and where did it come from? Alcohol is a natural substance formed by the reaction of fermenting sugar with yeast. The production of alcohol started about 10,000 years ago. It all started around the Black and Caspian Seas with wine, and slowly made its way around the surrounding areas. Mesopotamia and Egypt were thriving with wine productions by 3,000 B. C. (Narconon). A thousand years later, a Roman God, Dionysus, started appearing in the literature, and was the god of the grape harvest. Then, about 700 years after that, in addition to wine, India started manufacturing beer. This new production spread rapidly, and the Hebrews adopted the new beverage for many different new medicines. After that, the Jews began to use wine and beer in sacred rituals and ceremonies. Although some cultures accepted alcohol, others rejected it completely. Because these alcoholic beverages were spreading so quickly, they raised curiosity. A medical school in Italy began doing experiments, and finally developed something called distillation- a purer, stronger alcohol (Narconon). From Italy, these new drinks spread to England and Scotland, and eventually found their way over to America. Drunkenness became a huge problem in America, so the government passed the Prohibition Act of 1920. Originally, the eighteenth amendment to the U. S. Constitution prohibited the manufacture, sale, transport, import, or export of all alcoholic beverages. Upon its ratification by the states, Congress voted its approval in 1919. Thus the law was passed, and became known as the National Prohibition Act of 1920 (American Medical Association). The eighteenth amendment was repealed in 1933, which made the Prohibition Act null and unenforceable. After prohibition, most states restricted the minimum legal drinking age to twenty-one. Between 1970 and 1975, twenty-nine states lowered the minimum legal drinking age to eighteen, nineteen, or twenty. These changes were made when other activities, such as voting, were lowered. In between September 1976 and January 1983, the minimum legal drinking age for every state was set at the age of twenty-one. Although this is the law in our country, it is also incredibly easy for minors to obtain alcohol. As always, there are different ways to work around the law. These are issues that must be addressed. Some of these ways include a fake I. D. , a minor giving someone money to go buy it for them, going somewhere that will sell to minors, or even stealing it from their parents liquor cabinet. A fake I. D is fairly cheap and also easy to get if you know the right people. For the most part, if you were a minor trying to get alcohol you could go up to any random person, and eight times out of ten that person would go buy it for you. There are also places minors could go to buy it themselves like little gas stations around the lower socioeconomic societies. The reason that these gas stations will sell to minors is because it increases their sales, and because they will get little penalty for selling to minors. If they do get fined for it, the fine isn’t enough to make them stop. Alcohol generally is not secured in most homes so there is easy access for minors who have no fears about taking it from their parents. There has also been the increasing trend of parents not only providing alcohol, but encouraging its use in the home, under the assumption that minors will do it anyway and it’s better to do so in a supervised, safe environment. Underage drinking is one of the biggest problems that the U. S. faces, and is now considered a public health problem. Young adults have the highest prevalence of alcohol consumption than any other age group (Century Council). They also drink more heavily, experience more negative consequences, and engage in more harmful activities. Drinking at any age can have some of the worst effects on you and the people around you. Many young teens that experiment with alcohol believe there are no consequences to their actions. It is actually quite the opposite. Alcohol is associated with driving under the influence, violence and aggressiveness, sexual activity, smoking, and poor school performance. There are all of these problems, and then some that all started with alcohol. Driving under the influence or a DUI is classified under two categories, and can be given out if the person is under the influence of an intoxicating drink or a combination of an alcoholic beverage and drugs. There are felonies and misdemeanors. The difference between a misdemeanor and a felony is misdemeanor DUI charges means that the charge involved no injury or property damage, and the penalty can be up to 6 months in jail. A felony has injury and/or property damage, and the penalty could be up to three years in a state prison. This number fluctuates depending on the number of misdemeanors or felonies a person has had in the past. These laws are in place to not only protect the youth in America, but to also ensure that other innocent people on the roads do not get hurt. There are plenty of accidents that come from texting and driving already (which is the equivalent to drinking and driving) that to lower the drinking age, I think, would cause more alcohol-induced accidents. Underage drinking already contributes to more than 4,700 automobile wrecks a year (Centers for Disease Control and Prevention), and studies have shown that every twenty-two minutes someone will die of an alcohol related traffic accident (First Eagle Insurance Services). Although you probably think that it could never happen to you, other studies have shown that everyone has a forty percent chance of being in an accident involving alcohol use at some point in their life (Drug Free World). â€Å"Vehicle crashes remain the leading cause of death for minors age 15-20 years old† (Century Council). Aside from drinking and driving, there is also a two-way association between alcohol consumption and violence or aggressiveness. While individual behavior is shaped in large part by the environment, it is also manipulated by biological factors, and ultimately directed by the brain, but the brain is affected if large amounts of alcohol are consumed. The consumption of alcohol may promote aggressiveness and lead to victimization, which in turn leads to excessive consumption of alcohol. Violence and aggressive behaviors are those that are threatening, hostile, or damaging in a physical or nonphysical way. There have been multiple studies conducted that show there is a link between violent crimes and alcohol consumption. In 2012, the percentages of violent offenders who were drinking at the time of the offense were: â€Å"eighty-six percent of homicide offenders, thirty-seven percent of assault offenders, sixty percent of sexual offenders, up to fifty-seven percent of men, and twenty-seven percent of women involved in marital violence, and thirteen percent of child abusers† (NIAAA). A lot of times alcohol is accompanied by cigarettes, marijuana, or other hardcore drugs. Many researchers hypothesize that the ethanol in alcohol triggers a feeling of pleasure, and those feelings are reinforced when nicotine is added to the mix. Others think that those who abuse one substance will be more inclined to abuse other substances. Nicotine lowers blood alcohol concentration, so therefore a person who is smoking and drinking simultaneously would have to consume more alcohol in order to reach intoxication. Most people react differently to alcohol than others do. A lot of this has to do with the person’s age, gender, race/ethnicity, physical condition (weight, fitness level etc. ), amount of food consumed before drinking, use of drugs/prescription medications, and family history of alcohol problems. Usually when there is a family history of alcohol problems you will often see a history of some other type of disease linked to it. Some of these include: breast cancer, oral cancer, heart disease, strokes, diabetes, and cirrhosis of the liver. Twenty percent of alcohol is absorbed directly through the stomach walls into the bloodstream, and reaches all organs and tissues of the body within moments. The other eighty percent is processed through the gastrointestinal system. It is considered a drug, and is a sedative depressant of the central nervous system (Reeves). Alcohol can damage the dendrites at the end of a nerve cell causing disorder to brain functions. It is also capable of rupturing blood capillaries and veins. Aside from damaging nerves and veins, it can also damage the liver. It stops the liver’s ability to process fats, and can cause disease. The high sugar content in some alcoholic or mixed beverages can lead to hypoglycemia and predispose one to diabetes. Alcohol can also alter sleep patterns, basic motor functions, thoughts, and emotions. The consumption of alcohol on or at an above average rate can lead to alcoholism. Women metabolize alcohol more slowly than men. Because it stays in a womans bloodstream longer, it can cause more cellular damage of the kind that can trigger cancer. Alcohol also influences blood levels of estrogen and other hormones in ways that may make cancer more likely. For example, â€Å"compared to women who dont drink at all, women who have three alcoholic drinks per week have a 15% higher risk of breast cancer. Experts estimate that the risk of breast cancer goes up another 10% for each additional drink women regularly have each day. Girls ages 9-15 who have 3-5 drinks a week have 3 times the risk of developing benign breast lumps†(Breastcancer. org). These benign breast lumps can be a precursor to breast cancer. From this it is easy to see that the younger that someone starts consuming alcohol, the increased risk of cancer and loss of life is more likely. It might be easy to dismiss this issue as one of personal choice or preference. This discounts the social impact of drinking on society. â€Å"Alcohol costs American employers an estimated $134 billion in productivity losses, mostly due to missed work† (Ensuring solutions. org). The impact is not only economical though. Missed work impacts every worker at a job who must work that much harder to accomplish their work tasks. It also can decrease teamwork and morale due to resentment from the missed time at work, therefore decreasing productivity as well. Additionally, alcohol impacts every workers paycheck in other ways. As a rule, workers in America pay taxes on their pay as part of the social contract. These taxes are used for a variety of federal projects, such as ensuring a strong infrastructure, including maintenance of our highway system. â€Å"Alcohol related crashes costs the public $114. 3 billion annually† (MAAD). This is money that could be spent improving our roadways, bridges, and mass transit systems. This would also address shortfalls in other areas of the government budget, such as possibly addressing the furlough of air traffic controllers due to the current sequester. Not only is alcohol affecting society in terms of road safety, it is impacting air safety too. These quotes and statistics are not specifically for underage drinkers but as a sampling of society as a whole we can see that if adults are unable to drink heavily and prolonged without negative effects the same should be true of minors who have not yet developed full brain capacity and critical thinking skills. It is not just physical and social effects that are felt by people who overuse or abuse alcohol. â€Å"Among high school students, those who use alcohol are five times more likely to drop out than those who dont use alcohol. Alcohol is implicated in more than 40 percent of all college academic problems and in 28 percent of all college dropouts† (Alcoholcostcalculator. org). This has a ripple effect. High school and college dropouts on average earn less than those with secondary and post secondary degrees. This not only impacts the immediate quality of life it has long term effects reaching into retirement. Social Security is based on lifetime earned income. With the reduced earning potential of not having a diploma or degree underage drinkers set themselves up for living on a fixed income once they become old or infirm. This is not the only economic impact. A quick look at Rehabilitation Centers shows price ranges from $2,000-$30,000 for a 28 day stay. This does not include continuing aftercare. There are also legal fees for DUIs or Public Intoxication citations, plus bar tabs prior to the cessation of drinking. â€Å"Out of every $100 American consumers spend, about $1 goes to alcohol† (Vo). The average household income is around $50,000 per year, meaning that on average $500 a year is spent on alcohol, for an approximate lifetime average of $35,000. â€Å"In 2007 the death toll from teen drunk driving accidents was 1,393† (Drug Free World). The economic impact of funeral expenses, which on average total around $6,000, is nothing in terms of emotional cost. Many parents who lose a child end up divorcing, tearing apart families in the process. This may also lead to alcohol or other drug abuse in the parents or siblings, resulting in further economic, social, and societal impacts. It’s a vicious cycle and one that could be avoided by continuing to keep the drinking age at the current level. There are numerous warning signs that a minor may have an issue with underage drinking and it is important for those involved in the minor’s life to recognize these to curb an issue before it begins. These include physical, emotional, family, school, and social problems. Parents, teachers, and friends should look for physical signs such as fatigue, red and glazed eyes, or a lasting cough. Emotional indicators include personality changes, sudden mood changes, irritability, irresponsible behavior, low self esteem, poor judgment, and depression. The minor may start more arguments, break more rules and withdraw from their family. There will be a decreased interest in school, drop in grades, increased absences, truancy, and a rise in discipline issues. The minor may show a big social change, with new friends, a change in style of dress, and possible problems with the law. This list is not exhaustive, but from the examples given it shows that underage drinkers have a wealth of issues that will affect them negatively for quite some time. With all of this in mind, I do not feel that lowering the legal drinking age would be in our county’s best interest. The government has these laws in place to keep our country and the people in it safe, and if these laws were to change it would send our country into a downward spiral. I feel that the rates of alcohol induced traffic accidents, rates of violent crimes related to alcohol, rates of certain types of diseases, and much more would upsurge drastically. I also feel that if our government doesn’t address these issues with more force and power, minors will keep doing what they have been doing and nothing will change.

Macbeth and the Witches Essay example -- essays research papers

Macbeth: The Witches’ Responsibility for Macbeth’s Actions The three witches that are introduced at the beginning of the play are responsible for the introduction of the ideas that caused Duncan’s death and Macbeth’s destruction but not for Macbeth’s actions themselves. They recount to Macbeth three prophecies; that Macbeth will be: 1) Thane of Cawdor, 2) Thane of Glamis, and 3) King. Macbeth welcomes the ideas spawned from the witches’ prophecies, which is what triggered the spiral of events in this story. Macbeth eventually followed through with killing King Duncan. It was sometimes thought that the witches had the ability to reverse the natural order of things. This brings to the play the idea of fate and the role it has in the play. One can wonder if Macbeth ever had a chance of doing what was right after he heard the witches’ prophecies. However, it is more realistic to believe that Macbeth was responsible for his own actions throughout the play and in the end it was he that made the final decisions. T he witches could predict the future, they can add temptation, and influence Macbeth, but they cannot control his destiny. Macbeth creates his own misery when he is driven by the guilt of his actions. This causes him to become insecure about his actions, which causes him to commit more murders. The witches offer great enticement, but in the end, it is each individual’s decision to fall for the temptation, or to be strong enough to resist their appeal. The three witches are...
