Question

Is there any method of calculating paramagnetic or dimagnetic behaviour of an molecule other than MOT(Molecular orbital theory)??

Answer 1

simple Trick : -

Count the total electrons in the molecule

Paramagnetic- if total no. of electrons in the molecule are 10,16 or odd electrons then the molecule is paramagnetic.

Diamagnetic- if total no. of electrons are even except 10 & 16 then the molecule is paramagnetic .
