stir the solution in the conical vial while it is in the reflux condenser. The vigorous stirring is to ensure the interaction between the 1-hexene‚ the HBr‚ and the tetrabutylammonium bromide. Tetrabutylammonium bromide is used as a phase catalyst (one that helps the reactants move into the same phase phase) to help proceed the reaction faster since HBr and 1-hexene are the aqueous and organic phases respectively. The use of a reflux condenser is also crucial for the success of the reaction. The reflux

Introduction.- Majority of the time‚ to prepare alkyl halides is via the nucleophilic substitution reactions of alcohols. SN2 reaction is the type of reaction used in this lab experiment. Our objective was to see how a primary alkyl halide reacted with an alcohol. We did a conversion of n-butanol to 1-bromobutane. Br- ions is the nucleophile for this reaction which is generated from an aqueous solution of NaBr. The catalyst that converted the OH functional group of butanol to a better leaving group

The purpose of this experiment was to successfully produce stilbene dibromide by using a more sustainable approach‚ which would prevent less environmental issues. This was done by brominating trans-stilbene and then using the elimination process on the dibrominated product. This process is considered “greener” compared to the original bromination procedures. In order to create the alkyl halides‚ which are able to undergo chemical transformations more readily than the carbon-carbon double bond‚ onto
