 (a)

Interpretation Introduction

Interpretation: The steps involved in the reaction mechanism for the given set of reactions should be determined.

Concept Introduction:

${\text{S}}_{\text{N}}\text{1}$Reaction: it is a nucleophilic substitution reaction in which the rate determining step depends on one reactant. First step is the formation of more stable carbocation which is followed by the attack of nucleophile. Formation of more stable carbocation and the leaving group present in the substrate plays very important role in the reactivity of ${\text{S}}_{\text{N}}\text{1}$ reaction.

The loss of leaving group followed by the attack of nucleophile of the given substrate in ${\text{S}}_{\text{N}}\text{1}$ reaction is considered as the core (main) steps.

Carbocation: it is carbon ion that bears a positive charge on it.

Leaving group: it is a fragment that leaves substrate with a pair of electrons via heterolytic bond cleavage.

Nucleophile: donates pair of electrons to positively charged substrate resulting in the formation of chemical bond.
