Q. Nitrogen is relatively inactive element because

AIPMTAIPMT 1992The p-Block Elements - Part2

Solution:

Dinitrogen $(N_2)$ is chemically unreactive at ordinary temperature. The N-N bond in nitrogen molecule is a triple bond $(N \equiv N)$ with a bond distance of 109.8 pm and bond dissociation energy of $946 kJ mol^{-1}$. The low reactivity of nitrogen is due to fairly high bond dissociation energy of the molecule.
