A SN1 Reaction: Synthesis of tert

A SN1 Reaction: Synthesis of tert-Butyl Chloride Supplementary Material Experiment Notes: 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

Dichloromethane

Dichloromethane (methylene chloride DCM) is metabolized via two pathways in humans: mixed-function oxidases (MFO) and glutathione-S:-transferase (GST) Most likely the carcinogenicity for DCM is related to metabolic activation of DCM via the GST pathway However as the two pathways are competing the metabolic capacity for the MFO pathway in vivo is also of interest in risk assessment for
