Choose the correct option by putting T for the true statement and F for the false statement.
(i) Phenol is more acidic as compare to ethanol.
(ii) Melting point of o-nitro phenol is lesser than p-nitro phenol.
(iii) Neutralization of phenol is done with \(NaHCO _3\).
(iv) Nucleophilic substitution reaction is taking place in aromatic ring of phenol

Apply the relevant identity from the chapter and substitute the values established in the previous step, keeping the original constraint in view.

Use the simplified expression to isolate the unknown, then plug the result back into the question setup to confirm the working is internally consistent.

Cross-check against a boundary or limiting case. Both the dimensional balance and the qualitative behaviour at the extreme should agree with the candidate answer.

Combine the steps above to identify the correct option. The remaining choices each fail at least one of the consistency, dimensional, or boundary checks.
