(A)Both X and Y are oxygen containing compounds.✓ Correct
(B)Y on heating with CHCl3/KOH forms isocyanide.
(C)Z reacts with Hinsberg's reagent.✓ Correct
(D)Z is an aromatic primary amine.
Answer: (A), (C)
Solution
From the reaction sequence shown:
(A) is correct: Both X and Y are oxygen-containing compounds based on the reaction pathway.
(B) is incorrect: The carbylamine test (CHCl₃/KOH forming isocyanide) is specific for primary amines, not Y.
(C) is correct: Z reacts with Hinsberg's reagent (benzenesulfonyl chloride), which is a test for amines. Primary and secondary amines react differently with this reagent.
(D) is incorrect: While Z is an amine, the structure shows it is not an aromatic primary amine based on the reaction sequence.
