Question:

Maximum bond angle at nitrogen is present in which of the following?

NO+2

NO3−

NO2

NO2−

Solution:

In the following table:
Molecule Number of bonding domains Number of lone pairs Hybridization Bond angle predicted from hybridization
NO+2 2 0 sp 180°
NO− sp2 1 120°
NO2 2 1 sp2 120°
NO2− 2 1 sp2 120°
The maximum bond angle at nitrogen is present in NO2+
Note: Where lone pair - bond-pair repulsion is present, the actual bond angle will be lower than the predicted value.
