Concept introduction:
Two atomic orbitals combine to form a bonding and an antibonding molecular orbital. Orbitals that lie on internuclear axis combine to form sigma
The molecular orbital formed by combination of
Electrons are filled in the molecular orbitals in increasing order of energy.
Bond order is determined by subtracting the number of electrons in antibonding orbitals from the number of electrons in bonding orbitals, divided by two.
Mathematically, bond order can be expressed as follows:
Here,
