Question

The number of \( 3{C} - 2{e}^- \) bonds present in diborane is:

• A. 1
• B. 2
• C. 3
• D. 4

Hint:

In diborane, boron atoms form three-center, two-electron bonds, which are electron-deficient bonding structures often found in boron compounds.

Answer 1

The Correct Option is C

Diborane (\( {B}_2{H}_6 \)) contains three \( 3{C} - 2{e}^- \) bonds. These bonds are formed between the boron atoms and the hydrogen atoms in diborane. In this compound, the boron atoms are involved in three-center, two-electron bonds, which are unique and different from normal covalent bonds. These bonds form due to the electron deficiency of boron. Thus, the number of \( 3{C} - 2{e}^- \) bonds in diborane is 3.
