Q. For the following reaction sequence, choose the correct option Benzene —(i) CH₃COCl, AlCl₃; (ii) NaOCl→ P + Q
A) Both P and Q are carbonyl compounds
B) If P is the sodium salt of a carboxylic acid, Q is a primary alcohol
C) P and Q are aromatic compounds
D) If P gives a carboxylic acid on acidification, Q gives a poisonous gas on exposure to air and light
Explanation
[Solution from source] Friedel–Crafts acylation gives acetophenone, which undergoes the haloform reaction with NaOCl to give sodium benzoate and chloroform. Sodium benzoate gives benzoic acid on acidification, and chloroform is slowly oxidised by air in light to poisonous phosgene (COCl₂). Answer (4).
