Question

Which among the following is not a borane?

• A. $B_{2} H_{6}$
• B. $B_{3} H_{6}$
• C. $B_{4} H_{10}$
• D. None of these

Answer 1

Answer: (B)

$B_{3} H_{6}$

Answer 2

Boranes are the stable covalent hydrides of boron having formula
$B _{n} H _{n+4}$ and $B _{n} H _{n+6}$.
$B _{n} H _{n+4}$ [If $n=2 ; B _{2} H _{6}$ ]
$B _{n} H _{n+6}$ [If $n=4 ; B _{4} H _{10}$ ]
Thus, $B _{3} H _{6}$ is not a borane.
