Interpretation:
The given species
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 orbital formed by the combination of
orbitals, forms bonding molecular orbital designated as
and antibonding molecular orbital
orbital forms corresponding molecular orbitals.
Molecular orbitals formed by the combination of
orbital form a bonding molecular orbital designated as
and an antibonding molecular orbital designated as
Molecular orbitals formed by combining
orbital form bonding molecular orbitals designated as
and
Electrons are filled in the molecular orbitals in the increasing order of energy.
Bond order is determined by subtracting the number of electrons in antibonding orbitals from the number of electrons in bonding and dividing the result by two.
Higher the bond order, more stable is the molecule and bond order zero indicates molecule is not stable.
