A C 4 H 8 Cl 2 → 373 K Hydrolysis B C 4 H 8 O B reacts with Hydroxyl amine but does not give Tollen's test. Identify A and B .

Options

  1. A2 , 2 -Dichlorobutane and Butanal
  2. B2 , 2 -Dichlorobutane and Butan- 2 -one
  3. C1 , 1 -Dichlorobutane and 2 -Butanone
  4. D1 , 1 -Dichlorobutane and Butanal

Correct answer

B. 2 , 2 -Dichlorobutane and Butan- 2 -one

Step-by-step solution

Aldehydes and ketones react with hydroxyl amine to form oximes but ketones do not react with Tollens reagent. Compound B ' ' does not gives Tollen's test due to presence of kenotic group but react with hydroxyl amine
