(a)
Interpretation:
The electronic configuration in molecular orbital term should be written for the given molecule chlorine monoxide
Concept Introduction:
Molecular orbital (MO) theory: is a method for determining molecular structure in which electrons are not assigned to individual bonds between atoms, but are treated as moving under the influence of the nuclei in the whole molecule.
According to this theory there are two types of orbitals,
- (1) Bonding orbitals
- (2) Antibonding orbitals
Electrons in molecules are filled in accordance with the energy; the anti-bonding orbital has more energy than the bonding orbitals.
The electronic configuration of oxygen molecule
The * represent the antibonding orbital

Atoms with unpaired electrons are called Paramagnetic. Paramagnetic atoms are attracted to a magnet.
Atoms with paired electrons are called diamagnetic. Diamagnetic atoms are repelled by a magnet
