Question

Which of the following statement is not true for diborane $\left(B_2{H}_6\right)$

• A. $B_2{H}_6$ is an electron deficient molecule
• B. Hybridization of B atoms is $s{p}^2$ and molecule is planar
• C. The electronic distribution of the bridge bond has a banana like appearance and is also called banana bond
• D. $B_2{H}_6$ contains four $2c-2e^{-}$ bonds and two $3c-2e^{-}$ bonds

Answer 1

The correct option is B Hybridization of B atoms is $s{p}^2$ and molecule is planar


$B_2{H}_6$ can be considered as hybrid structure of the following resonating structure.
$\underset{\left(I\right)}{\left[B{H}_2^{+}\right]\left[B{H}_4^{-}\right]}\leftrightarrow \underset{\left(II\right)}{\left[B{H}_4^{-}\right]\left[B{H}_2^{+}\right]}$
