The most appropriate reagent for conversion of C 2 H 5 CN into CH 3 CH 2 CH 2 NH 2 is :

The most appropriate reagent for conversion of

C_{2} H_{5} CN

into

{CH}_{3} {CH}_{2} {CH}_{2} {NH}_{2}

is :

${NaBH}_{4}$
${CaH}_{2}$
${LiAlH}_{4}$
$Na (CN) {BH}_{3}$

Solution

${CH}_{3} {CH}_{2} - C \equiv N \overset{{LiAlH}_{4}}{\to} {CH}_{3} {CH}_{3} - {CH}_{2} - {NH}_{2}$

${NaBH}_{4}$ does not reduce $R - CN$ .
