Vedclass · Answer

(B) The reaction of a Lewis acid like $BCl_{3}$ with $LiAlH_{4}$ in an ether medium produces diborane $(B_{2}H_{6})$,which is a highly toxic gas.$4BCl_{3} + 3LiAlH_{4} \rightarrow 2B_{2}H_{6} + 3AlCl_{3} + 3LiCl$When diborane $(B_{2}H_{6})$ is heated with ammonia $(NH_{3})$,it forms borazine $(B_{3}N_{3}H_{6})$,which is commonly known as inorganic benzene.$3B_{2}H_{6} + 6NH_{3} \rightarrow 2B_{3}N_{3}H_{6} + 12H_{2}$Thus,the toxic gas is $B_{2}H_{6}$.

$A$ Lewis acid '$X$' reacts with $LiAlH_{4}$ in ether medium to give a highly toxic gas. This gas when heated with $NH_{3}$ gives a compound commonly known as inorganic benzene. The gas is
