Chapter 14, Problem 63P

Interpretation Introduction

Interpretation: The benzylic halide that reacts faster in an ${\text{S}}_{\text{N}}1$ reaction is to be explained.

Concept introduction: The substitution reaction involves the replacement of one functional group by other functional group. In nucleophilic substitution an electron rich species attack the species that is deficient in electrons. The electrophile and the leaving group together form a substrate. The nucleophile attacks over the substrate and there occurs removal of leaving group from the substrate.
