Question

Diborane reacts with ammonium chloride on heating to give (A), B-trichloroborazine; reduction of (A) with NaBH₄ gives (B), an inorganic ring compound isoelectronic and isostructural with benzene. The maximum number of atoms present in one plane in compound (A) is :

TestHub · Accepted Answer

3B₂H₆ + 6NH₄Cl → 2B₃N₃H₃Cl₃ + 18H₂, so (A) = B₃N₃H₃Cl₃ (B-trichloroborazine) and (B) = borazine, B₃N₃H₆. Like benzene, the ring and all its substituents are coplanar: 3 B + 3 N + 3 Cl + 3 H = 12 atoms in one plane.
