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.© BrainMass Inc. brainmass.com September 25, 2018, 10:52 pm ad1c9bdddf - https://brainmass.com/chemistry/general-chemistry/mo-theory-dissociation-energy-78955
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) ...
The solution explains the dissociation energy of neutral nitrogen and oxygen with reference to the MO theory.
