The conversion of phenol to benzene in the presence of zinc involves:
Correct answer: B. Reduction
- A. Oxidation
- B. Reduction
- C. Dehydroxylation
- D. Dehydrogenation
Explanation
Benzene can be prepared from phenols too through their reduction. In this process, vapors of phenol are passed over heated zinc dust. Zinc dust reduces them to form benzene.

About Phenols
Phenols contain a hydroxyl group directly bonded to an aromatic ring, making them more acidic than alcohols because the phenoxide ion is resonance-stabilised. Reactions include ionisation with bases, electrophilic substitution, bromination, nitration and oxidation, with attention to the difference between phenols and aliphatic alcohols.
