#### The correct order of magnetic moments (spin only values in B.M.) among is(Atomic nos.: Mn = 25, Fe = 26, Co = 27) Option 1) Option 2) Option 3) Option 4)

As we learnt in

Calculation of spin only magnetic moment -

where n = no. of unpaired electron

- wherein

1.   has  ion and its magnetic moment is

2.  has  ion and its magnetic moment is

3.  has  ion with strong field ligand and its magnetic moment is zero.
