The d-electron configurations of and are and , respectively. Which one of the following will exhibit minimum paramagnetic behaviour?
At, nos. Cr=24, Mn=25, Fe=26, Co=27)
As we learnt in
Magnetic Moments (spin only) -
where n= number of unpaired electron.
- wherein
Number of unpaired and corresponding magnetic moments
is awork field ligand.
The config of in the complex is
Similarly, for Cr2+
For Mn2+
For Fe2+
has min. no. of impaired s & a it will exchibit minimum paramagnetic behaviour.
