Concept introduction:
Two atomic orbitals undergo a combination process in order to form a bonding and an anti-bonding molecular orbital. Orbitals that lie on the internuclear axis combine to form sigma molecular orbitals, and orbitals parallel to each other combine to form molecular orbitals.
The molecular orbitals formed by the combination of
orbitals are a bonding molecular orbital, designated by
orbital forms corresponding molecular orbitals.
The molecular orbitals formed by the combination of
orbitals area bonding molecular orbital, designated by
The molecular orbitals formed by combining
orbitals are bonding molecular orbitals, designated by
and
and
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, and dividing by two.
Higher the bond order, more stable is the molecule. Zero bond order indicates the molecule is not stable.
