Among the following ions, which one has the highest paramagnetism?
A.[Cr (H2O)6]3+
B.[Fe (H2O)6]2+✓ Correct
C.[Cu (H2O)6]2
D.[Zn (H2O)6]2+
Explanation
Paramagnetic compounds are those compounds which have one or more unpaired electrons. Among the following compounds 2+ 2 6 [Fe(H O) ] contain 4 unpaired electron which is more than the other complexes and the magnetic moment of this complex will be highest.
