Higher bond energy.

Vedclass · Answer

(A) $N_2$ and $CN^-$ are isoelectronic species,both having $14$ electrons. $N_2$ has a very high bond dissociation energy $(941 \ kJ \ mol^{-1})$ due to the presence of a strong triple bond $(N \equiv N)$. This high bond energy makes $N_2$ chemically inert under normal conditions. In contrast,$CN^-$ is an ion and is more reactive due to the presence of a negative charge and different electronic environment compared to the neutral $N_2$ molecule.

$CN^-$ and $N_2$ are isoelectronic,but $N_2$ is chemically inert compared to $CN^-$. The reason is:
