No2 resonance.

NO₂⁺ is sp hybridized with no lone pairs and linear geometry. Thus, bond angle will be equal to the ideal bond angle of sp hybridization i.e. 180°. NO₂ is sp² hybridized with a lone electron which exerts a less repulsion than a lone pair of electrons, so two bonding oxygen atoms are able to spread out more leading to bond angle greater ...3. Six electrons are used to form three bonding pairs between the oxygen atoms and the carbon: 4.
