Zaitsev’s rule. Zaitsev’s rule states that the major product of a β-elimination reaction is the most stable alkene [1].Acid-Catalyzed Dehydration is the elimination of a molecule of water from adjacent carbon atoms. An alcohol can be converted to an alkene by dehydration‚ which is often brought on by heating the alcohol with either 85% phosphoric acid or concentrated sulfuric acid [1]. The objective of this experiment is to dehydrate 3-methyl-3-pentanol to obtain the product mixture of isomeric alkenes

Experiment #7 Fall 2014 Dehydration of an alcohol NAME Nick Weinberger POSTLAB 1. Show the mechanism for the dehydration of -tetralol under conditions employed in the lab. Show all intermediates‚ and show electron flow with arrows. 2. What general mechanism most likely applies to this reaction (SN2‚ E2 etc)? E1 3. Why was acid employed in this reaction? The acid was used to protonate the leaving group (OH) to form water which is a much better leaving

Dehydration of Alcohols Abstract The dehydration of cyclohexanol to cyclohexene can be done through fractional distillation. Once the fraction has been collected it must then be dried. The dried distillate is finally tested to determine whether or not it has been dehydrated. The three tests used were infrared spectroscopy‚ Bromine chemical test and Bayer’s chemical test. The infrared spectroscopy showed a large narrow peak at 3062.12(cm-1) and 3020.71(cm-1) which indicates that there is a double

Dehydration james November 18‚ 2010 Dehydration Water is an essential part to maintaining a healthy body and weight. Without the proper intake of water‚ the body becomes dehydrated and it begins to pull it from other places including from your blood. “This causes the closing of some smaller vessels (capillaries)‚ making your blood thicker‚ more susceptible to clotting‚ and harder to pump through your system. This can have serious implications in hypertension‚ high cholesterol‚ and heart

Assignment | Dehydration | Miesha K. Branch | Human beings require water to survive. Individuals have to understand the importance of staying hydrated and the warning signs of dehydration in order to live long healthy lives. Water and fluids are the main element in staying hydrated and healthy Dehydration is the loss of salts and water that can cause many complications or health issues in human beings. Dehydration can occur when an individual doesn’t consume enough fluids such as water‚

Cyclohexene Synthesis by Dehydration Reaction of Cyclohexanol Gjulia Vokrri 02-15-2013 Abstract Alkenes can be produced by heating and dehydrating an alcohol in the presence of a strong acid. The purpose of this experiment was to synthesize cyclohexene by dehydration of cyclohexanol and to detect the presence of a double bond in the alkene. The dehydration reaction using distillation was

There were no differences at admission between the groups in age‚ sex‚ previous types of feeding‚ previous duration of diarrhea‚ use of antibiotics‚ weight‚ height‚ weight-height percentile‚ prevalence of fever‚ overall status‚ degree of dehydration‚ and percentage of in-versus outpatients. Duration of diarrhea after enrollment was 71.9 ± 35.8 hours in group A versus 58.3 ± 27.6 hours in group B (mean ± SD;P = 0.03). In rotavirus-positive children‚ diarrhea lasted 76.6 ± 41.6 hours in group

Dehydration Sci/241 Abbe Breiter-Fineberg 4/1/2012 Passing out‚ lethargy‚ constipation‚ dry mouth and even dry eyes are very few symptoms in the long list of signs to tell us that we are dehydrated. Being dehydrated is potentially very bad and if not taken care of a person can end up in the hospital or even dying. Many things can cause dehydration including drinking too much alcohol or simply not drinking enough water. Without ample amounts of water our bodies cannot function correctly‚

IntroductionA dehydration reaction of an alcohol results in an alkene. This type of reaction requires an alcohol‚ an acid catalyst and heat. Generally strong concentrated acids‚ like sulfuric acid and phosphoric acid‚ are used as the acid catalyst.The acid catalyst protonates the alcohol‚ to make a much better leaving group. Weakest bases make the best leaving groups‚ so once the alcohol is protonated the leaving group leaves and produces in a carbocation and water. In order to form the double bond
