In diborane the two `H-B-H` angles are nearly

A

`60^(@), 120^(@)`

B

`95^(@), 120^(@)`

C

`95^(@), 150^(@)`

D

`120^(@), 180^(@)`

Text Solution

Verified by Experts

The correct Answer is:
B
In diborane, `H_(t)-B-H_(t)` and `H_(b)-B-H_(b)` bond angles are `120^(@)` and `97^(@)` respectively (`H_(t)=` terminal hydrogen atoms, `H_(b)` = bridged hydrogen atoms).
