Vedclass · Answer

(A) The reaction of diborane $(B_2H_6)$ with ammonia $(NH_3)$ at low temperature results in the formation of an ionic adduct $X$, which is diammoniate of diborane, $[BH_2(NH_3)_2]^+[BH_4]^-$. The chemical equation is: $B_2H_6 + 2NH_3 \longrightarrow [BH_2(NH_3)_2]^+[BH_4]^-$. Upon heating, this compound $X$ undergoes decomposition to form borazine $(B_3N_3H_6)$ and hydrogen gas $(H_2)$: $3[BH_2(NH_3)_2]^+[BH_4]^- \xrightarrow{\Delta} 2B_3N_3H_6 + 12H_2$.

Diborane reacts with ammonia to form $X$, which on heating gives $H_2$ and borazine. $X$ is
