Which of the least bond angle ?

A

`NH_(3)`

B

`BeF_(2)`

C

`H_(2)O`

D

`CH_(4)`

Text Solution

Verified by Experts

The correct Answer is:
C
`H_(2)O,NH_(3) and CH_(3)` all are `sp^(3)` hybridized but due to two lp - lp repulsions, bond angle in `H_(2)O (104.5^(@))` is lower than in `NH_(3) (107^(@))` which has one Ip and `CH_(4) (109^(@) 28.)` which has no lp. `BeF_(2)` on the other hand, has sp hybridization and hence has a bond angle of `180^(@)`.
