Question

Which one of the following is more paramagnetic Fe2+ or Fe3+ ? Explain.​

Answer 1

Answer:

Fe3+ is more paramagnetic because valency is high

Answer 2

Paramagnetic behaviour tends to increase as the number of unpaired electrons increases. Therefore, the ferric ion (Fe3+) is more paramagnetic than the ferrous ion (Fe2+). It can be noted that the ferric ion is more paramagnetic because it has 5 unpaired electrons.
