2-bromopropanoic acid when heated with alcoholic KCN gives and organic compounds which on futher acid hydrolysis gives the compounds A, hence A will be

Options

A. `underset(OH) underset(|)(CH_(3)-CH-COOH)`
B. `underset(CH_(2)NH_(2)) underset(|)(CH_(3)-CH-COOH)`
C. `underset(NH_(2)) underset(|)(CH_(3)-CH-COOH)`
D. `CH_(3)-CH(COOH)_(2)`

Answer

D

Explanation

`underset(2-"bromopropanoic acid") underset(Br) underset(|)(CH_(3)-CH-COOH)overset((alc)KCN) to underset(2-"cyanopropanic acid") underset(CN) underset(|)(CH_(3)-CH-COOH)overset(H_(3)O^(+)) to underset(A) underset(COOH) underset(|)(CH_(3)-CHOOPH)`
