Chapter 8, Problem 8.13YT

Interpretation Introduction

Interpretation:

Which is the correct product of the given ${\text{S}}_{\text{N}}\text{2}$ reaction, A or B, is to be explained.

Concept introduction:

An ${\text{S}}_{\text{N}}\text{2}$ reaction takes place in one step in which the nucleophile attacks from the opposite side of the leaving group. Therefore, these reactions are stereospecific in the case of a chiral substrate. The mechanism of the ${\text{S}}_{\text{N}}\text{2}$ reaction involves a single step. Since the nucleophile attacks from the opposite side of the leaving group, the stereochemistry of the product is changed with inversion of configuration.
