Diborane reacts with ammonia under different conditions to give a variety of products. Which one among the following is not formed in these reactions?
Options
- AB ₂ H ₆ 2 NH ₃
- BB ₁₂ H ₁₂
- CB ₃ ~N ₃ H ₆
- D( BN )_n
Correct answer
B. B ₁₂ H ₁₂
Step-by-step solution
Diborane reacts with ammonia and gives different products under different reaction conditions as B ₂ H ₆+ (excess) NH ₃ temperature at low addition product B ₂ H ₆ 2 NH ₃ B ₂ H ₆+ (excess) NH ₃ high temperature boron nitride (resembles with graphite) ( BN )_n 1 ~B ₂ H ₆ : + 2 NH ₃ high temperature borazine (inorganic benzene) B ₃ ~N ₃ H ₆ Thus, B ₁₂ H ₁₂ is not the product of reaction between diborane and ammonia.
