Q. Find the total no. of unpaired $e^{-}$present in the following complexes
(I) $\left[Fe\left(CO\right)_{5}\right]$
(II) $\left[Fe\left(CN\right)_{6}\right]^{4-}$
(III) $\left[Cr\left(CO\right)_{6}\right]$
(IV) $\left[Mn\left(CN\right)_{6}\right]^{4-}$

Coordination Compounds

Solution:

$Mn^{2+}: 3d^{5} 4s^{0}$

Complexes (I, II, III) are diamagnetic hence they have no unpaired electrons.
