Options

  1. A1
  2. B2
  3. C3
  4. D4

Correct answer

B. 2

Step-by-step solution

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