Solution
The correct option is CNO<N2O3<N2O4<N2O5 The acidic nature of the oxides of nitrogen can be determined by the strength of the acid formed by the nitrogen oxide in water. The acidic strength of nitrogen oxides follows this order:
N2O<NO<N2O3<N2O4<N2O5
N2O5 forms nitric acid (HNO3) in water, which is a very strong acid.
