Which of the following is correct regarding phenol?
Correct answer: B. Phenol is less acidic than carboxylicacid
- A. Phenol and water are equally acidic
- B. Phenol is less acidic than carboxylicacid
- C. Phenol is less acidic than water
- D. Phenol is less acidic than ethanol
Explanation
Because the conjugate base of a carboxylic acid is more stable than that of phenol, carboxylic acids are stronger acids than phenols, meaning phenol is less acidic than carboxylic acids.

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.
