Question

Reaction of diborane with excess ammonia at low temperature gives initially:

• A. B₂H₆·NH₃
• B. Borazole
• C. [BH₂(NH₃)₂]⁺[BH₄]⁻
• D. B₂N₄H₁₀

Hint:

When diborane reacts with ammonia, it forms an ionic compound as a result of electron donation from ammonia.

Answer 1

The Correct Option is C

Diborane reacts with ammonia to form an adduct, \([BH_2(NH_3)_2]^+ [BH_4]^-\), under low-temperature conditions.
