(a)

Interpretation Introduction

To determine: The member among the given pair of compounds that react faster by the ${\text{S}}_{\text{N}}1$ mechanism.

Interpretation: The member among the given pair of compounds that react faster by the ${\text{S}}_{\text{N}}1$ mechanism is to be predicted.

Concept introduction: The replacement or substitution of one functional group with another different functional group in any chemical reaction is termed as substitution reaction. There are two types of substitution reaction.

The nucleophilic reaction contains only a substrate as a reactant not a nucleophile which means a unimolecular nucleophilic reaction is termed as ${\text{S}}_{\text{N}}1$ reaction.

The nucleophilic reaction contains a substrate as well as a nucleophile as the reactants which mean a bimolecular nucleophilic reaction is termed as ${\text{S}}_{\text{N}}\text{2}$ reaction. It includes the bond-making and bond-breaking steps. This is a one-step reaction in which both nucleophile and substrate participate in the rate determining step.
