The Preparation of 1- Bromobutane Introduction... Aim : To prepare 1-Bromobutane. Background : The most common way of preparing alkyl halides‚ which are very useful intermediates in syntheses‚ is the replacement of the OH group of an alcohol by a halogen. This replacement is a nucleophilic substitution reaction‚ and alcohols do not undergo nucleophilic substitution reactions because hydroxide ison is strongly basic and a poor leaving group. However‚ alcohols readily undergo

PREPARATION OF TIN TETRAIODIDE 09/06/2012 Introduction The objective of this project was to prepare tin tetraiodide through the following reaction: Sn+2I2∆SnI4 and to measure the melting point of tin tetraiodide. Tin tetraiodide was recrystallized after the synthesis. The percent yield and the theoretical yield of tin tetraiodide were calculated. Recrystallization is to further improve the purity of tin tetraiodide. The solvent is carefully chosen to be toluene in order to maximize the recovery
