Answer 1

Diborane $\left(B_2{H}_6\right)$ has a three centre electron pair bond. Two types of hydrogen i. e., terminal hydrogen and bridging hydrogen are present in this structure.

Boron -Terminal hydrogen ⇒ Two centre electron pair bond

Boron -Bridging hydrogen ⇒ Three centre electron pair bond.
