Chapter 16.SE, Problem 29MP
Interpretation Introduction

Interpretation:

Given that sulfonation of aromatic ring with SO3 and H2SO4 is reversible. The product benzenesulfonic acid on heating with H2SO4 yields benzene. The mechanism of the desulfonation reaction is to be given and the electrophile involved is to be identified.

Concept introduction:

Sulfonation is a reversible process. Therefore the mechanism of desulfonation is exactly reverse of the sulfonation process.

To propose:

The mechanism for the desulfonation of benzenesulfonic acid to benzene on heating with H2SO4. The electrophile involved is to be identified.
