Answer:
- In case of nitrogen, N2 → N2+ + e-
Electron is lost from bonding MO and the bond order decreases from 3 to 2.5.As a result, bond dissociation energy decreases and the bond length increases.
- In case of oxygen, O2 → O2+ + e-
Electron is lost from antibonding MO and the bond order increases from 2 to 2.5. As a result, bond dissociation energy increases but bond length decreases.
