Question

$C{N}^{-}$ and $N_2$ are isoelectronic. But in contrast to $C{N}^{-},N_2$ is chemically inert because of:

• A. smaller $N-N$ bond energy
• B. larger $N-N$ bond energy
• C. low inoziation enthalpy
• D. none of these

Answer 1

The correct option is B larger $N-N$ bond energy

both have 14 electron so they are isoelectronic but due to large bond energy $N_2$ is a inert specie.
