Mark the incorrect statement in the following.
The bond order in the species O2, O-2 and O-2decreases as O-2>O2>O-2
The bond energy in a diatomic molecule always increases when an electron is lost
Electrons in antibonding MO contribute to repulsion between two atoms
With increase in bond order, bond length decreases and bond strength increases
