Chapter 6, Problem 21P

Interpretation Introduction

Interpretation:

The ${\text{S}}_{\text{N}}2$ reaction, which takes place more rapidly in a protic solvent, is to be identified.

Concept introduction:

In organic chemistry, nucleophilic substitution consists of bimolecular reactions, one-step mechanisms, and the carbocation will not form. Thus, this type of reaction is known as ${\text{S}}_{\text{N}}2$ reaction.

In an alkyl halide, the reaction takes place between halogen atoms and alkanes in order to form halogenated hydrocarbons.
