Chapter 8, Problem 8.21P

Interpretation Introduction

Interpretation:

A reasonable mechanism for the reaction in Your Turn $\text{8}\text{.15}$ is to be determined.

Concept introduction:

${\text{S}}_{\text{N}}\text{2}$ reaction is bimolecular nucleophilic substitution reaction. Two reacting species are involved in the rate determining step of the reaction. In the reaction mechanism, simultaneous bond breaking and bond formation is involved. ${\text{S}}_{\text{N}}\text{2}$ reaction requires the attack of the nucleophile from the side opposite to the leaving group, so that the product has an inversion of configuration.
