Introduction The purpose to of this experiment is to carry out the alkylation of sodium saccharin with iodo-ethane and analyze the product mixture to determine the structure of the major product. Sodium saccharin is made from the base catalyzed de protonation of saccharin. This nucleophilic reaction is special because the nucleophilic atom can be oxygen or nitrogen and the leaving group is iodide ion. The solvent used in this reaction is very important for determining the rate of nucleophilic
