The magnetic moment of a transition metal compound has been calculated to be3.87 BM. The metal ion is

Options:

Answer:
C
Solution:

The magnetic moment, μs=n(n+2)BM where n is the number of unpaired electrons. 

Cr+2 : Ar, 3d4, 4s° n=4, μ=4(4+2)=24=4.89 BMMn+2 : Ar, 3d5, 4s° n=5, μ=5(5+2)=35=5.91 BMV+2 : Ar, 3d3, 4s° n=3, μ=3(3+2)=15=3.87 BMTi+2 : Ar, 3d2, 4s° n=2, μ=2(2+2)=8=2.82 BM
