Chapter 23, Problem 23.39P

Interpretation Introduction

Interpretation:

The most likely site(s) of electrophilic aromatic substitution in the given molecule are to be indicated.

Concept introduction:

The electrophilic aromatic substitution reaction rate increases with an increase in electron density around the ring. The electron donating groups activates whereas the electron withdrawing groups deactivates the aromatic ring. The electron donating groups increases the electron density at ortho-para position and thus they are ortho-para directing. The electron withdrawing groups decrease electron density at ortho/para and have comparatively greater electron density at meta position, thus they are meta directing.
