Question

Benzene sulphonic acid can be converted back to benzene via desulphonation. What specific conditions drive this reversible reaction backward?

Answer: C

💡 Solution & Explanation

Sulphonation is an equilibrium reaction. Heating benzene sulphonic acid with superheated steam (or boiling dilute mineral acid) drives the equilibrium backwards, replacing $-SO_3H$ with $H^+$ to yield benzene.
