Why Nitrogen dioxide (NO2) is coloured but Dinitrogen tetraoxide (N2O4) is colourless?

Nitrogen dioxide (NO2) has unpaired electrons therefore it absorbs light from visible and radiate brown colour whereas Dinitrogen tetra oxide (N2O4) does not have unpaired electrons so it does not absorb light from visible region.

Why Nitrogen dioxide (NO2) dimerises to form Dinitrogen tetraoxide (N2O4)?

Nitrogen dioxide (NO2) contains odd number of valence electrons. It behaves as a typical odd molecule. On dimerisation, it is converted to stable Dinitrogen tetra oxide (N2O4) molecule with even number of electrons.

Why Nitrogen (N2) is less reactive at room temperature?

Because of strong pπ–pπ overlap Nitrogen has triple bond between two nitrogen atoms (N≡N) which has high bond dissociation energy. So it is less reactive.

Why Nitrogen is fairly inert gas?

Nitrogen exists as triply bonded (pπ–pπ overlap) diatomic non polar molecule. Due to short inter nuclear distance between two nitrogen atoms the bond strength is very high. It is therefore, very difficult to break the bond.

Why nitrogen shows catenation properties less than phosphorus?

Catenation power of nitrogen is less because N-N bond is weaker than the single P-P bond. N-N single bond is weaker than P-P bond is due to smaller size of nitrogen atom there is stronger inter electronic repulsion between nitrogen atoms hence it form strong pπ–pπ multiple bond and become diatomic molecule.
