High bond dissociation enthalpy

(D) The nitrogen molecule $(N_2)$ consists of two nitrogen atoms linked by a triple bond $(N \equiv N)$.Due to the presence of this triple bond,the bond dissociation enthalpy of $N_2$ is extremely high $(941.4 \ kJ \ mol^{-1})$.This high bond energy makes the molecule very stable and chemically inert under normal conditions.
