Chapter 10, Problem 10.32P

Interpretation Introduction

Interpretation:

The complete, detailed mechanism for the given reaction is to be drawn.

Concept introduction:

A much better way to convert an alcohol into an alkyl halide is to use ${\text{PCl}}_{\text{3}}$. The conversion of an alcohol into an alkyl halide using ${\text{PCl}}_{\text{3}}$ occurs readily at the OH group bonded to a primary carbon atom. The two step mechanism occurs which consists of back-to-back ${\text{S}}_{\text{N}}\text{2}$ steps.
