Question
Which of the following metal ions will form complexes with the same magnetic momentand geometry irrespective of the nature of ligands?
Options
A.Ni2+
B.Fe2+
C.Cu2+
D.Co2+
Solution
Cu2+ forms complexes with the same magnetic moment and geometry irrespective of the nature of ligand. It can be explained by electronic configuration.
Cu2+
It has 9 electrons in 3d shell. Hence any incoming ligand whether it is strong or weak will result imn the formation of same. geometry (if number of ligands is same) because any ligand can do nothing with this umpaired e- in 3d shell. Moreover, the complex formed will have same magetic moment due to this unpaired e- .
