Phenol is changed into cyclohexanol by the following method:
Correct answer: A. Hydrogenation
- A. Hydrogenation
- B. Reaction with formaldehyde
- C. Nitration
- D. Halogenation
Explanation
Option A is correct as Phenol is a benzene ring with an OH group bonded to one carbon, if we "hydrogenate" the ring, the carbons will use the free valence electrons and bond to hydrogen forming cyclic hexanol.

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.
