Question

A compound A reacts with lithium aluminium hydride (LiAIH₄) to form a boron hydride (B). On hydrolysis with water, B forms boric acid and with heating with ammonia it forms inorganic benzene (C). Identify A, B and C and write the chemical equations.

Answer 1

Since, compound A reacts with LiAlH₄ to form boron hydride. So, compound A may be boron trifluoride and compound B is diborane. Diborane on heating with NH₃ to form inorganic benzene (C), which is borazine. 

The chemical equations are shown as below-
