The correct set of the products obtained in the following reactions is (A)$RCN\overset{Reduction\ }{\rightarrow}$ (B)$\ RCN\underset{(II)H_{2}O}{\overset{{(I){CH}_{3}MgBr}_{\ }}{\rightarrow}}$ (C)$RNC\overset{\ Hydrolysis\ }{\rightarrow}$ (D)$RNH_{2}\overset{HNO_{2}\ }{\rightarrow}$ [table] A | B | C | D [/table]
A) [table] $2{^\circ}$amine | Methyl ketone | $1{^\circ}$amine | Alcohol [/table]
B) [table] $1{^\circ}$amine | Methyl ketone | $1{^\circ}$amine | Alcohol [/table]
C) [table] $2{^\circ}$amine | Methyl ketone | $2{^\circ}$amine | Acid [/table]
D) [table] $2{^\circ}$amine | Methyl ketone | $2{^\circ}$amine | aldehyde [/table]
Explanation
(b)
$(A)RCN\overset{Reduction}{\rightarrow}RCH_{2}NH_{2}$
$\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 1{^\circ}$amine
(B)[image:13_image206.emf]
$(C)\ RNC\overset{Hydrolysis}{\rightarrow}H - COOH + RNH_{2}$
$\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 1{^\circ}$amine
$(D)\ RNH_{2}\overset{HNO_{2}\ }{\rightarrow}\ ROH + N_{2} + H_{2}O$
