Question

Diborane reacts with ammonia under different condition to give a variety of products. Which of the following are formed in these conditions.

• A. $B_2{H}_6.2N{H}_3$
• B. $B_3{N}_3{H}_6$
• C. $(BN{)}_x$
• D. $H_{3}B{O}_3$

Answer 1

Answer: (A), (B), (C)

The correct options are
A

$B_2{H}_6.2N{H}_3$

B

$B_3{N}_3{H}_6$

C

$(BN{)}_x$

$B_2{H}_6+N{H}_3\underset{lowtemp}{\overset{excessN{H}_3}{\to }}{B}_2{H}_6.2N{H}_3\underset{hightemp.}{\overset{excessN{H}_3}{\to }}(BN{)}_x\underset{2N{H}_3:l{B}_2{H}_6}{\overset{2N{H}_3:1B_2{H}_6}{\to }}{B}_3{N}_3{H}_6$
