Question

The structure of diborane ($B_2{H}_6$) contains:

• A. Four $2C-2e$ bonds and two $3C2e$ bonds
• B. Two $2C-2e$ bonds and two $3C2e$ bonds
• C. Two $2C-2e$ bonds and four $3C2e$ bonds
• D. Four $2C-2e$ bonds and four $3C2e$ bonds

Answer 1

The correct option is A Four $2C-2e$ bonds and two $3C2e$ bonds

As shown in the figure, the structure of diborane consists of two $3C2e^{-}B-H$ bonds also called banana bonds, and four $2C2e^{-}$ normal covalent bonds
