Identify product B obtained in following reaction. $\mathrm{CH}_{3}-\mathrm{CH}_{3} \underset{\Delta}{\stackrel{\mathrm{HNO}_{2}}{\longrightarrow} \mathrm{A}} \xrightarrow[\text { ether }]{\mathrm{LiAlH}_{4}} \mathrm{B}$
  1. Ethanoic acid
  2. Ethanal
  3. Ethanol
  4. Ethanamine

Solution

$\begin{aligned} \mathrm{CH}_{3}-\mathrm{CH}_{3} & \stackrel{\mathrm{HNO}_{2}}{\rightarrow} \mathrm{A} \stackrel{\mathrm{LiAH}_{4}}{\text { ether }} \mathrm{B} \\ \mathrm{A} &=\mathrm{CH}_{3}-\mathrm{CH}_{2}-\mathrm{NO}_{2} \text {; Reduction by LiAiH }_{4} \text {; } \\ \mathrm{B} &=\mathrm{CH}_{3}-\mathrm{CH}_{2}-\mathrm{NH}_{2} \text { Ethanamine } \end{aligned}$
