Correct answer: B. Br2(aq)
- A. Tollen's reagent
- B. Br2(aq)
- C. NaHCO3
- D. HCl
Explanation
Phenol reacts with aqueous bromine to give a white precipitate, while ethanol does not react with bromine water. This provides a clear visual distinction between the two.

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.
