Question

$B$ reacts with hydroxyl amine but does not give Tollens' test. Identify $A$ and $B.$
$\underset{\left(C_4{H}_{8}C{l}_2\right)}{A}\underset{373K}{\overset{\text{Hydrolysis}}{\to }}\underset{\left(C_4{H}_{8}O\right)}{B}$

• A. 1,1-Dichlorobutane and 2-Butanone
• B. 2,2-Dichlorobutane and Butan-2-one
• C. 2,2-Dichlorobutane and Butanal
• D. 1,1-Dichlorobutane and Butanal

Answer 1

The correct option is B 2,2-Dichlorobutane and Butan-2-one


Compound $B$ does not give Tollens' test due to presence of kenotic group but reacts with hydroxyl amine.
