Question
What is the correct order of spin only magnetic moment of Mn2+, Cr2+ and V2+ :-
Options
A.Mn2+ > V2+ > Cr2+
B.V2+ > Cr2+ > Mn2+
C.Mn2+ > Cr2+ > V2+
D.Cr2+ > V2+ > Mn2+
Solution
Mn2+ Cr2+ V2+
No. of unpaired electrons 5 4 3
Mag. moment ∝ No. of unpaired electrons
No. of unpaired electrons 5 4 3
Mag. moment ∝ No. of unpaired electrons
