Conversion of Alcohols to Alkyl Halides Ankita Patel August 6‚ 2013 Introduction This lab consisted of the conversion of alcohols into alkyl halides through common substitution methods. These methods include SN1 and SN2 mechanism‚ both of which can occur for this type of reaction. For both reactions‚ the first step of protonation will be to add hydrogen to the –OH group and then the rest of the reaction will proceed according to the type of mechanism. SN1 reactions form a cation intermediate

Experiment 1: Preparation of 1-Bromobutane and Reactivity of Alkyl Halides Objective: The purpose of this lab is to prepare 1-bromobutane from 1-butanol in an acid-catalyzed substitution reaction. While the reaction would be expected to occur as SN2 due to the primary nature of the substrate‚ because H2SO4 is used as a solvent‚ the conditions are very polar and the reaction can proceed via an SN1 reaction. The main objective is to obtain test results to determine the mechanism of the reaction

SYNTHESIS OF AN ALKYL HALIDE S.M. BLANCAFLOR1 1INSTITUTE OF BIOLOGY‚ COLLEGE OF SCIENCE UNIVERSITY OF THE PHILIPPINES‚ DILIMAN‚ QUEZON CITY 1101‚ PHILIPPINES DATE SUBMITTED: 3 JANUARY 2012 DATE PERFORMED: 8 DECEMBER 2011 ------------------------------------------------- ABSTRACT Alkyl halides are molecules which have a carbon atom attached to a halogen atom (e.g.‚ chlorine‚ iodine‚ or bromine.) Alkyl halides are very important since they are used in many of the products used today

Relative Reactivity of Alkyl Halides Introduction Nucleophilic substitution of alkyl halides can proceed by two different mechanisms – the SN2 and the SN1. The purpose of the experiment was to identify the effects that the alkyl group and the halide-leaving group have on the rates of SN1 reactions‚ and the effect that the solvent has on the rates of SN1 and SN2 reactions. The SN1 mechanism is a two-step nucleophilic substitution‚ or unimolecular displacement. In the first step of the mechanism

Title: Preparation of Cyclohexene from Cyclohexanol Aim: To prepare an alkene‚ cyclohexene‚ by the dehydration of an alcohol‚ cyclohexanol‚ and better understand the processes that take place during this reaction. Introduction: One of the common ways of preparing an alkene is through the dehydration of an alcohol. In this experiment cyclohexanol is dehydrated to prepare cyclohexene while using sulfuric acid as a catalyst. A bromine test can be later done to ensure that the end product is
