The reactions of phenol in which the ring is involved includeall EXCEPT:
Correct answer: B. Esterification
- A. Nitration
- B. Esterification
- C. Sulphonation
- D. Bromination
Explanation
Nitration, sulphonation, and bromination are all electrophilic aromatic substitution reactions that occur on the benzene ring of phenol. Esterification, however, is a reaction that occurs at the hydroxyl (-OH) group, not on the ring itself.

About Alcohols and Phenols
Alcohols are classified as primary, secondary or tertiary and studied through their hydrogen bonding, acidity, oxidation and reactions with active metals, acids and halogenating agents. Phenols require separate treatment because the hydroxyl group is attached to an aromatic ring, making their acidity and electrophilic substitution different from ordinary alcohols.
