Diborane reacts with $\mathrm{HCl}$ in the presence of $\mathrm{AlCl}_3$ and liberates

  • Correct answer
    A
    $$ \mathrm{H}_2 $$
  • B
    $\mathrm{Cl}_2$
  • C
    $\mathrm{BCl}_3$
  • D
    $\mathrm{Cl}_2$ and $\mathrm{BCl}_3$

Solution

Diborane reacts with $\mathrm{HCl}$ in the presence of $\mathrm{AlCl}_3$ catalyst and liberates $\mathrm{H}_2$ gas. $$ \underset{\mathrm{B}_2 \mathrm{H}_6}{ }+\mathrm{HCl} \stackrel{\mathrm{AlCl}_3}{\longrightarrow} \mathrm{B}_2 \mathrm{H}_5 \mathrm{Cl}+\mathrm{H}_2 \uparrow $$

Hence, the correct answer is option: 'A'.
