Q. Benzyl amine cannot be prepared by
A) $C_{6}H_{5}CONH_{2}\underset{ether}{\overset{{\ LiAlH}_{4}\ }{\rightarrow}}$
B) $C_{6}H_{5}CH_{2}CONH_{2} + Br_{2} + KOH \rightarrow$
C) $C_{6}H_{5}CN\overset{\ LiAlH_{4}\ }{\rightarrow}$
D) $C_{6}H_{5}CH_{2}NC\overset{\ LiAlH_{4}\ }{\rightarrow}$
Explanation
(d)
${(a)\ C}_{6}H_{5}CONH_{2}\underset{ether}{\overset{{LiAlH}_{4}}{\rightarrow}}C_{6}H_{5}{CH}_{2}{NH}_{2}$
Benzylamine
(b)$\ C_{6}H_{5}CH_{2}CONH_{2}\overset{{Br}_{2}/KOH}{\rightarrow}C_{6}H_{5}{CH}_{2}{NH}_{2}$
Benzylamine
$(c)C_{6}H_{5}CN\overset{LiAlH_{4}}{\rightarrow}C_{6}H_{5}{CH}_{2}{NH}_{2}$
Benzylamine
(d) $C_{6}H_{5}CH_{2}NC\overset{LiAlH_{4}}{\rightarrow}C_{6}H_{5}CH_{2}NHCH_{3}$
