When an inorganic compound X having 3c - 2e^ − as well as 2 c - 2...

This problem is based on preparation of inorganic benzene and structural charactristics of diborane. Student must be familiar with concept of bonding in diborane to solve this problem. Identify the compounds and complete the chemical reaction using information supplied in the question.

$\mathop{{B}_{2} {H}_{6}}_{\left(\text{X}\right)} + {2NH}_{3} \left(\text{excess}\right)\mathop{→}_{Δ}^{\text{Low}\text{temperature}} {B}_{2} {H}_{6} ⋅ 2{NH}_{3} \mathop{→}_{Δ}^{473\text{K}} \mathop{{B}_{3} {N}_{3} {H}_{6}}_{\text{borozole}\left(\text{Y}\right)}$

Y has structure similar to benzene (inorganic benzene)

${B}_{2} {H}_{6} + {NH}_{3}$\left(\text{excess}\right)\mathop{→}_{Δ}^{\text{High}\text{temperature}} \mathop{{\left(\text{BN}\right)}_{X}}_{\text{boron}\text{nitride}\left(\text{Z}\right)}
