Interpretation Introduction

Interpretation:

The curved-arrow mechanism for the conversion of benzenesulfonic acid into benzene and ${\text{H}}_{\text{2}}{\text{SO}}_{\text{4}}$ with hot water is to be predicted.

Concept introduction:

The replacement of hydrogen atom attached to a carbon atom of electron-rich benzene ring by another electrophile is known as electrophilic aromatic substitution reaction. Some electrophilic aromatic substitution reactions are reversible in nature they convert back the product electrophilic aromatic substitution reactions into its reactant.
