Chapter 23, Problem 23.57P

Interpretation Introduction

Interpretation:

The electrostatic potential maps of benzene and pyrrole are given. If the electrostatic potential map of pyrrole consistent with the ring being activated or deactivated relative to benzeneis to be explained.

Concept introduction:

Aromatic rings other than benzene can also undergo electrophilic aromatic substitution including naphthalene, furan, pyrrole, and pyridine. Pyrrole is activated toward electrophilic aromatic substitution. The nitrogen electron pair is part of the aromatic system in pyrrole and donates electron density via resonance.
