Although CN ⁻ ion and N ₂ molecule are isoelectronic, yet N ₂ molecule is chemically inert because of

Options

  1. Apresence of more number of electrons in bonding orbitals
  2. Blone bond energy
  3. Cabsence of bond polarity
  4. Duneven electron distribution.

Correct answer

C. absence of bond polarity

Step-by-step solution

In nitrogen molecule, both the nitrogen atoms have same electronegativity. So it has zero polarity and hence less tendency to break away and form ions.
