A (C4H8Cl2) Hydrolysis 373 K B (C4H8O) B reacts with Hydroxyl amine but does not give Tollen's test. Identify A and B

1. 1,1-Dichlorobutane and 2-Butanone
2. 2,2-Dichlorobutane and Butanal
3. 1,1-Dichlorobutane and Butanal
4. 2,2-Dichlorobutane and 2-butane-one

Correct answer: 2,2-Dichlorobutane and Butanal

Solution

The correct option is right because 2,2-Dichlorobutane undergoes hydrolysis to form Butanal, which reacts with hydroxylamine but does not give a positive Tollen's test, indicating it is an aldehyde rather than a ketone.
