(ii) Benzoic acid and Phenol

Open in App

Solution

(i) Tollen's reagent test: Add ammoniacal solution of silver nitrate (Tollen's Reagent) in both the solutions. Butanal gives silver mirror whereas Butan-2-one does not.

(ii) Benzoic acid and phenol can be distinguished by ferric chloride test. Add neutral $F e C l_{3}$ in both the solution, phenol forms violet colour but benzoic acid does not.
