Borazine, also known as inorganic benzene, can be prepared by the reaction of 3 -equivalents of " X " with 6 -equivalents of " Y ". " X " and " Y ", respectively are

Step-by-step solution

Reaction of ammonia with diborane gives initially B 2 H 6 . 2 NH 3 which is formulated as BH 2 NH 3 2 +   BH 4 -   ; further heating gives borazine, B 3 N 3 H 6 known as ''inorganic benzene'' in view of its ring structure with alternate BH and NH groups. 3 B 2 H 6 + 6 NH 3 → 3 BH 2 NH 3 2 + BH 4 - → Heat 2 B 3 N 3 H 6 + 12 H 2
