Solution:
When N2+ is formed from N2, the electron is lost from the bonding molecular orbital and thus the bond order decreases. Consequently, the bond distance increases.
When O2+ is formed, the electron is lost from an antibonding molecular orbital. Obviously, the bond order increases and the bond distance decreases.
