Among the following compounds that can be most readily sulfonated is
Correct answer: A. Phenol
- A. Phenol
- B. Benzene
- C. Nitro-benzene
- D. Benzoic acid
Explanation
Phenol can be most readily sulfonated because it has an -OH group attached directly to the benzene ring, which activates the ring towards electrophilic substitution reactions like sulfonation. The lone pairs on the oxygen atom in the -OH group can donate electron density to the benzene ring, making it more reactive towards electrophiles.

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.
