Mark the incorrect statement in the following.
The bond order in the species O2,
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.
Strongest hydrogen bonding is shown by
H2S
