Arenediazonium salt + warming with water III. Yields phenol and N ₂ gas Choose the correct answer from the options given below:

Step-by-step solution

Primary aliphatic amines react with nitrous acid ( HNO ₂ ) to form highly unstable aliphatic diazonium salts, which immediately decompose to yield alcohols and nitrogen gas. (A-I) Primary aromatic amines react with HNO ₂ at low temperatures ( 273-278 K ) to form arenediazonium salts, which are stable under these conditions due to resonance. (B-II) When an arenediazonium salt solution is warmed with water, it undergoes hydrolysis to yield phenol and nitrogen gas. (C-III) Therefore, the correct matching is A-I, B-II,
