Question

During the concentration of white bauxite by Serpeck's process, a useful gas is liberated. This gas when treated with diborane while heating gives an aromatic compound along with hydrogen gas. Select the incorrect statement about the compound.

TestHub · Accepted Answer

The useful gas liberated in Serpeck's process is NH₃. When NH₃ reacts with diborane (B₂H₆) upon heating, it forms borazine (B₃N₃H₆), which is an aromatic compound.

Borazine has a planar structure, and all B and N atoms are sp² hybridized. Back bonding is present through delocalized $π$ -bonds. In NH₃, nitrogen is sp³ hybridized, while in borazine, nitrogen is sp² hybridized. Thus, the number of bond-forming orbitals changes for nitrogen.

Therefore, statement D is incorrect.
