The following points are important regarding the oxides of nitrogen.

(a) All oxides of nitrogen except

N_{2} O_{5}

are endothermic because large amount of energy is required to dissociate the stable molecule of oxygen and nitrogen.

(b) The small electronegativity difference between oxygen and nitrogen makes N-O bond easily breakable to give oxygen and hence oxides of nitrogen are said to be better oxidizing agents.
