    Use simple MO Theory (LCAO-MO) to explain why the dissociation energy of neutral N2 is greater than the N2+ ion, but that the dissociation energy of the O2+ ion is greater than the O2 neutral.

    In order to understand fully the structures of N2,N2+,O2 and O2+ we should know the electronic configurations of these species.

    N2 and N2+

    Molecule of N2 has 10 electrons distributed in bonding and antibonding molecular orbitals as under:

    ORBITALS NUMBER OF ELECTRONS
    sigma 2s(bonding) 2
    sigma 2s (antibonding) 2
    pi-2p (bonding) ...

    Solution Summary

    The solution explains the dissociation energy of neutral nitrogen and oxygen with reference to the MO theory.
