Question

Which one of the following compounds does not belong to the family of boranes?
$[$ Hint: General formulae of boranes are $B_n{H}_{n+4}and{B}_n{H}_{n+6}.]$

• A. $B_5{H}_9$
• B. $B_5{H}_{10}$
• C. $B_5{H}_{11}$
• D. $B_6{H}_{10}$

Answer 1

The correct option is B $B_5{H}_{10}$

Boranes have the general formulae as $B_n{H}_{n+4}$ or $B_n{H}_{n+6}$.

Hence, $B_5{H}_{10}$ is not a borane.
