The number of $3 \mathrm{C}-2 e^{-}$bonds present in diborane is
- A1
- Correct answerB2
- C3
- D4
Solution
The structure of diborane is
In this structure, there are two $3 \mathrm{C}-2 e^{-}$bonds. 3 atoms, $\quad \mathrm{B}-\mathrm{H}-\mathrm{B}$ share two electrons and form an angular geometry, leading bent bond, also known as banana bond.
