The pairs of species of oxygen and their magnetic behaviors are noted below. Which of the following presents the correct description?
- Both diamagnetic
- Both paramagnetic
- Both paramagnetic
- Both paramagnetic
As we learnt in
Magnetic behaviour of molecule -
If all the molecular orbitals in a molecule are doubly occupied, the substance is diamagnetic
- wherein
However if one or more molecular orbital are singly occupied it is paramagnetic e.g. O2
Electronic configuration of molecule
Since there are 2 unpaired electrons in & degenerate orbitals, so, is paramagnetic.
Similarly for molecule, we have
Since, there is 1 unpaired electron in orbital,
is paramagnetic.
Option 1)
- Both diamagnetic
This option is incorrect.
Option 2)
- Both paramagnetic
This option is incorrect.
Option 3)
- Both paramagnetic
This option is correct.
Option 4)
- Both paramagnetic
This option is incorrect.
