Chapter 6, Problem 65AP

(a) Sketch the occupied MOs of the valence shell for the ${\text{N}}_{\text{2}}$ molecule. Label the orbitals as $\sigma$ or $\pi$ orbitals, and specify which are bonding and which are antibonding.

(b) If one electron is removed from the highest occupied orbital of ${\text{N}}_{\text{2}}$ , will the equilibrium $\text{N}—\text{N}$ distance become longer or shorter? Explain briefly.
