Solution

The correct option is C $N O_{2}$
In $N O_{2},$ there is upelectron so it is paramagnetic in nature. It is an odd electron system containing 23 eletcrons.

Nitrogen forms largest oxides as it is capable of forming stable multiple bonds with oxygen. They range from

N_{2} O

(O.S of nitrogen +1) through

N O, N_{2} O_{3}, N_{2} O_{4}

N_{2} O_{5}

(O.S of nitrogen +5).

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.

N_{2} O_{5}

, all are gases at ordinary temperature.

N_{2} O_{3}

is stable only at a lower temperature (253 K).

N_{2} O

N O

which are neutral oxides, all are acidic oxides that dissolve in water forming corresponding oxyacids.

(e) They are also a good example of illustrating the concept of resonance.
