Chapter 18, Problem 18.2P

Interpretation Introduction

Interpretation: The curved arrows which show the conversion of other two resonance structures of benzene to the substitution product $\left(\text{PhE}\right)$ by removal of a proton with $\text{B}$ are to be drawn.

Concept introduction: Most of the organic structures cannot be represented using single Lewis structure. Therefore, there exists more than one Lewis structure for representing a molecule or ion. These structures are known as resonance structures. Benzene is an aromatic compound. It is a stable compound due to resonance.
