* Bent or Angular: The molecule has a bent or angular shape.

* Hybridization: The nitrogen atom undergoes sp2 hybridization.

* Bonding: There is a double bond between the nitrogen atom and one of the oxygen atoms, and a single bond between the nitrogen atom and the other oxygen atom.

* Lone Pair: The nitrogen atom has one lone pair of electrons.

* Resonance: NO2 exhibits resonance, meaning the double bond is delocalized across both nitrogen-oxygen bonds. This results in an average bond order of 1.5 for each N-O bond.

Key Properties:

* Paramagnetic: NO2 is paramagnetic due to the presence of an unpaired electron on the nitrogen atom.

* Pollutant: NO2 is a significant air pollutant, contributing to acid rain and respiratory problems.
