The bond angles of NH(3),NH(4)^(o+) and ...

The bond angles of `NH_(3),NH_(4)^(o+)` and `overset(Theta)(NH_(2)` are in the order .

A

`NH_(2)^(-)gtNH_(3)gtNH_(4)^(+)`

B

`NH_(4)^(+)gtNH_(3)gtNH_(2)^(-)`

C

`NH_(3)gtNH_(2)^(-)gtNH_(4)^(+)`

D

`NH_(3)gtNH_(4)^(+)gtNH_(2)^(-)`

Text Solution

Verified by Experts

(b) As the number of lone pairs of electrons increases, bond angle decreases. Therefore, the order of bond angle is
`{:(NH_(4)^(+),gt,NH_(3),gt,NH_(2)^(-)),(nolp,,1lp,,2lp):}`
