हिन्दीFor the following reaction sequence, choose the correct option \( \text{Benzene} \xrightarrow[\text{ii. } \text{NaOCl}]{\text{i. } \text{CH}_3\text{COCl}, \text{ AlCl}_3} \text{P} + \text{Q} \)
View Answer & Solution
Correct answer · Option C
If \( \mathbf{P} \) gives a carboxylic acid on acidification, \( \mathbf{Q} \) gives a poisonous gas on exposure to air and light.
Explanation
Acetylation of benzene yields acetophenone (P), which upon haloform reaction with NaOCl gives sodium benzoate. Acidification yields benzoic acid. Q is chloroform (CHCl3), which forms phosgene gas upon exposure to air and light.
