Interpretation Introduction

Interpretation:

Poor solvent for ${\text{S}}_{\text{N}}2$ has to be identified.

Concept Introduction:

Solvent for ${\text{S}}_{\text{N}}2$ reaction:

The polar protic solvents are induce the formation of carbocation in substitution reaction so polar aprotic solvents are commonly used for ${\text{S}}_{\text{N}}2$ reactions.
