Question

Sulphonation differs from most of the electrophilic aromatic substitution reactions with the fact that the reaction :

• A. is reversible
• B. requires Lewis acid as a catalyst
• C. is explosive
• D. takes place at high temperature

Answer 1

Answer: (A)

is reversible

Sulfonation differs from most of the electrophilic aromatic substitution reactions with the fact that the reaction is reversible as all the intermediate steps in the mechanism are equilibrium steps.
