The cyanide ion `CN and N_(2)` are isoelectronic, but in contrast to `CN^(-), N_(2)` is chemically inert, because of

A

Low bond energy

B

Absence of bond polarity

C

Unsymmetrical electron distribution

D

Presence of more number of electron in bonding orbitals

Text Solution

Verified by Experts

The correct Answer is:
D
`N_2` contains `(N-=N)` triple bond , difficult to break . Therefore less reactive , inert
