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

The Causes and Effects of Gender Imbalance in Asia By Tom Farrer Throughout this paper I will focus on the phenomenon of the gender imbalance in Asia. I will begin by assessing the current situation and researching the various causes which have led to it. I shall then analyse the possible consequences to follow and conclude with an outlook to the future. According to the United Nations the recommended sex ratio at birth (SRB) for a country is 107‚ meaning that for every 100 females born‚ 107 males

Understand how homeostatic mechanisms operate in the maintenance of an internal environment Homeostasis is keeping the body balanced to allow cells to function‚ despite external environment. Homeostasis is important because the cells‚ blood and tissue fluids can change by slowing down or even stop a vital chemical reaction. Its aim is to keep the body to stay the same‚ at a normal condition. Negative feedback is when change is detected; there are steps when change is detected to get it back

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
