The `ONO` bond angle is maximum in

Options

A. `NO_(3)^(-)`
B. `NO_(2)^(-)`
C. `NO_(2)`
D. `NO_(2)^(+)`

Answer

D

Explanation

`NO_(3)^(-) has sp^(2)` hybridisation and three reasonating
Structures
Hence , ONO bond anlge `= 120^(@)`
`NO_(2)^(+)` has no unshared electron . It has only bond
pairs in two directions . Hence, shape is linear
`(underset(. .)overset(. .)O=overset(+)N=underset(. .)overset(. .)O)` with bond angle = `180^(@)`
`NO_(2)` has one unshared electron whereas `NO_(2)^(-)` has
one unshared electron pair . Hence , in `NO_(2)^(-)` , the
repulsion on the bond pairs are more and angle is less
