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

A 5 year old girl Jenny has presented to the Emergency Department with her mother‚ she is suffering from a variety of symptoms including wheezing and vomiting‚ a dry mouth‚ and a temperature of 39.7 degrees Celsius. Vomiting is when the person is excreting all food from there stomach via the mouth using forces from the oesophagus and stomach (Hockenberry & Wilson‚ 2007). The rationale for choosing this symptom is that vomiting is a clear sign that the body is trying to get rid of a pathogen‚ with

connection between different systems in the body and how they use water to maintain proper health and function. We will discuss what happens to the body when we intake too much water (water toxicity)‚ likewise when we lose or intake too little (dehydration). Why is water essential to health maintenance? Water is the “great regulator” in the body. It has several functions: to dissolve nutrients and move them throughout the body‚ to flush and carry waste particles from the body‚ and to

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

Lab Protocol #8 - Dehydration of 3‚3-dimethyl-2-butanol KEYWORDS: alkenes‚ E2‚ E1‚ carbocation stability‚ elimination A. Introduction. The dehydration of alcohols is an ELIMINATION reaction that is commonly used to form alkene molecules. The mechanism for the dehydration of alcohols consists of transforming the –OH functional group into a better leaving group by using a strong acid to protonate the alcohol. After –OH has been transformed into –OH2+‚ it becomes easier to break the σ-bond between the

Dysphagia and dehydration after a Stroke: A Literature Review Background. Stroke is a major cause of mortality in the United Kingdom; it is the third biggest killer in the UK (National audit office 2005) around 53‚000 people die every year from this long term condition. (Scarborough et al 2009) In people under the age of 75 it is a main cause of premature mortality with 1 in 20 dying because of an acute stroke and the complications that arise. In socially deprived areas a person is 3 times more

When the body suffers from acute or sever dehydration‚ the blood flow and blood pressure drop due to a lack of water and oxygen in the blood. Dehydration results when the body loses more water than it has taken in. Naturally this will cause the muscles and nerve function to literally burn out due in part to profuse sweating after exertion. How ever you can become dehydrated without any physical exercise. If you have the stomach flu‚ and are suffering from water loss (due to a combination of vomiting

3/26/2012 Part A: Dehydration of 1-butanol & 2-Butanol/Part B: Dehydrobromination of 1-Bromobutane & 2-Bromobutane Abstract The objective of this experiment is to successfully perform a dehydration of 1-butanol and 2-butanol‚ also dehydrobromination of 1-bromobutane and 2-bromobutane to form the alkene products 1-butene‚ trans-2-butene‚ and cis-2-butene. The dehydration reactions react under and acid-catalysis which follows an E1 mechanism. It was found that dehydration of 1-butanol yielded
