The magnetic properties of oxygen and ozone are different. Explain.

Answer»

SOLUTION :Oxygen is a MOLECULE with even number of ELECTRONS. But it is paramagnetic . Its magnetic moment is 2.83BM corresponding to two unpaired electrons. Molecular orbital THEORY explains the presence of unpaired electrons.
Ozone is diamagnetic. Its magnetic moment is ZERO. Ozone molecule has no unpaired electrons.
