Ozone is :

  • A.Non-magnetic
  • B.Ferromagnetic
  • C.Paramagnetic
  • D.Diamagnetic

Answer: D

Ozone is diamagnetic.

All the electrons in \(\mathrm{O_3}\) are paired, so it has no permanent magnetic moment and is weakly repelled by a magnetic field. Ordinary oxygen, \(\mathrm{O_2}\), is the opposite: it has two unpaired electrons in its antibonding \(\pi^*\) orbitals and is paramagnetic.
