Step-by-step solution

The coplanarity of N 2 O 4 results from a delicate balance of the repulsive forces, which favour the skew structure, and of the effects of bonding which favour the planar structure. NO 2 is a bent molecule. The   N 2 O 5   molecule is a trigonal planar molecule. N 2 O has a linear, unsymmetrical structure that may be thought of as a hybrid of two resonance forms.
