A SN1 Reaction: Synthesis of tert-Butyl Chloride

This lab experiment proposes the synthesis of an alkyl halide by reacting the corresponding alcohol with a hydrogen halide in an easy and inexpensive SN1 reaction. 1,2 tert-Butanol reacts readily with HCl and forms the corresponding tert-butyl chloride at room temperature. SN1 mechanisms are unimolecular because its slow step is unimolecular.
