Chapter 15, Problem 28P

Interpretation Introduction

Interpretation:

The reason for the failure of the given synthesis is to be explained.

Concept introduction:

Benzene and substituted benzene undergo electrophilic substitution reactions in the presence of an electrophilic reagent. The electrophilic substitution on the substituted benzene occurs on the basis of the nature of the reagent present on the benzene ring. If the group is ortho-para directing, an ortho and para isomer will be formed as the product, and if the group is meta directing, a meta product is formed.
