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

Formation of an Alkene by Alcohol Dehydration Lab Report Balanced Chemical Equation for the Main Reaction Mechanism The acid-catalyzed dehydration of secondary and tertiary alcohols involves non-isolable carbocation intermediaries. In the first step of the of the reaction mechanism below‚ a phosphoric acid catalyst adds a proton to the oxygen atom of the alcohol to form an oxonium ion. The OH is converted to a better leaving group as the positive charge on the oxygen weakens the carbon-oxygen

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

Experiment 2: Dehydration of an Alcohol: Distillation and Gas Chromatography Preparation of Methylcyclohexenes Purpose: The basic purpose of this experiment is to carry out the dehydration of an alcohol and isolate the reaction products by distillation. Gas Chromatography will be utilized to analyze the reaction mixture. Table of Reagents: Compound (g) Molecular Weight (g/mol) Grams (g) Moles 6 mL of 2-methylcyclohexanol (C7H14O) 114.19 g/mol 6 mL x 0.943g = 5.66 g 1 mL 5.66 g x

Dehydration is when your body has lost too many fluids. Water is one of the most important nutrients to our body; the human body is from 55 percent to about 78 percent of water. The average person loses water consistently by doing everyday activities and sweating‚ breathing and eliminating waste. Water removes toxins and waste products from the body and puts nutrients into the body. Dehydration affects many people for many different reasons. Water has a HUGE effect on people when it comes to dehydration

we lack the necessary about of fluid‚ dehydration-which is when a person loses more bodily fluid than he or she takes in‚ occurs. Dehydration can occur quickly‚ gradually over a period of time. In this paper‚ I will discuss the various effects of dehydration on the human body. I will discuss the importance of water to our health‚ compare and contrast the various functions of electrolytes‚ potassium‚ and chloride in the body‚ research the effect of alcohol and caffeine on hydration levels and finally

Dehydration In 1994‚ thousands of starving people died in the Africa nation of Rwanda. It wasn’t lack of food that killed most of these people‚ but cholera‚ a bacterial infected that cripples the ability of intestinal mucosal cells to reabsorb water. The severe diarrhea that develops can kill in days‚ sometimes even hours. Dehydration is deadly. Dehydration is a deficiency condition that occurs when output of water exceeds intake. It is a great problem for athletes‚ military personnel‚ and certain
