Magnetic Moments (spin only) -

\sqrt{n\left ( n+2 \right )} where n= number of unpaired electron.

- wherein

Number of unpaired e^{-} s and corresponding magnetic moments

1\rightarrow 1.7\\2\rightarrow 2.8\\3\rightarrow 3.9\\4\rightarrow 4.9\\5\rightarrow 5.9

THe formula  \mu = \sqrt{n}\left ( n+2 \right )BM

transition metal complex have  d orbital and  d orbital can contain  5 unpaired max so

if n=5 the \mu= 5.92 BM example : Mn^{2+}complex

 


Option 1)

5.92

Option 2)

6.93

Option 3)

3.87

Option 4)
