Identify the product ' $\mathrm{B}$ ' in the following sequence of reactions. $\mathrm{CH}_3 \mathrm{Br} \stackrel{\mathrm{KCN}}{\longrightarrow} \mathrm{A} \stackrel{\mathrm{Na}^2 \mathrm{C}_2 \mathrm{H}_5 \mathrm{OH}}{\longrightarrow} \mathrm{B}$
  1. Methyl cyanide
  2. Ethylamine
  3. Methylamine
  4. Ethyl cyanide

Solution

$\mathrm{CH}_3 \mathrm{Br} \stackrel{\mathrm{KCN}}{\longrightarrow} \mathrm{CH}_3 \mathrm{CN} \stackrel{\mathrm{Na}_2 \mathrm{H}_5 \mathrm{OH}}{\longrightarrow} \mathrm{CH}_3-\mathrm{CH}_2-\mathrm{NH}_2$ Ethylamine
