Phenol reacts with calcium carbonate and evolve _?
Correct answer: D. None of these
- A. H2 gas
- B. CO2 gas
- C. O2
- D. None of these
Explanation
Phenol does not react with calcium carbonate (CaCO3) to evolve any gas. Phenol is a weak acid, and while it can be neutralized by strong bases like sodium hydroxide, it is not strong enough to react with weak acids like carbonic acid, which is formed when calcium carbonate dissolves in water.

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.
