Question:

$\text{The structure of diborane (B}_2\text{H}_6\text{) contains:}$

Options:

1. $\text{four 2C-2e}^- \text{ bonds and four 3C-2e}^- \text{ bonds}$
2. $\text{two 2C-2e}^- \text{ bonds and two 3C-3e}^- \text{ bonds}$
3. $\text{two 2C-2e}^- \text{ bonds and four 3C-2e}^- \text{ bonds}$
4. $\text{four 2C-2e}^- \text{ bonds and two 3C-2e}^- \text{ bonds}$

Solution:

$\text{Diborane (B}_2\text{H}_6\text{) has a structure with two bridging hydrogen atoms.}$ $\text{It contains four terminal B-H bonds (2C-2e}^-) \text{ and two bridging B-H-B bonds (3C-2e}^-\text{).}$
