The ONO bond angle is maximum in

1.	The ONO bond angle is maximum in
Answer» `NO_(3)^(-)` `NO_(2)^(-)` `NO_(2)` `NO_(2)^(+)` SOLUTION :`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
