For the following reaction sequence, choose the correct option
A
If P is the sodium salt of a carboxylic acid, Q is a primary alcohol.
B
P and Q are aromatic compounds.
C
If P gives a carboxylic acid on acidification, Q gives a poisonous gas on exposure to air and light.
D
Both P and Q are carbonyl compounds.
Explanation
Benzene + CH₃COCl/AlCl₃ gives acetophenone. On treatment with NaOCl, acetophenone undergoes haloform reaction to give: P = Sodium benzoate (C₆H₅COONa) Q = CHCl₃ On acidification: C₆H₅COONa + H⁺ → C₆H₅COOH CHCl₃ on exposure to air and light gives COCl₂ (phosgene), which is a poisonous gas. Hence option (C) is correct.
