Question

Consider the following sequence of reactions :
Compound[A] $\xrightarrow{\text{Reduction}} [B] \xrightarrow{HNO_2} CH_3CH_2OH $
The compound [A] is

• A. $CH_3 CH_2 CN$
• B. $CH_3 NO_2$
• C. $CH_3 NC$
• D. $CH_3 CN$

Answer 1

Answer: (D)

$CH_3 C \equiv N \xrightarrow [LiAIH_4] {Reduction}$
$CH_3 - \underset {B}{CH_2} - NH_2 \xrightarrow {HNO_2} CH_3 CH_2 OH$
1$^{\circ}$ am ine(Ethanamine)
$\therefore $ A is $CH_3CN.$
