${\left[Fe{\left(CN\right)}_6\right]}^{4-}$

${\left[Fe{\left(CN\right)}_6\right]}^{3-}$

${\left[Ti{\left(CN\right)}_6\right]}^{3-}$

${\left[Ni{\left(CN\right)}_4\right]}^{2-}$

${\left[Co{\left(CN\right)}_6\right]}^{3-}$

Among the given complexes, number of paramagnetic complexes in__________.

CN is a strong field ligand, so pairing occurs.

1. ${\left[Fe{\left(CN\right)}_6\right]}^{4-}$

So; it is diamagnetic

2. ${\left[Fe{\left(CN\right)}_6\right]}^{3-}$

So; it is paramagnetic.

3. ${\left[Ti{\left(CN\right)}_6\right]}^{3-}$

Ti³⁺ = 4s⁰3d¹

 It is paramagnetic

4. ${\left[Ni{\left(CN\right)}_4\right]}^{2-}$

It is diamagnetic

5. ${\left[Co{\left(Cn\right)}_6\right]}^{3-}$

Hence,  ${\left[Fe{\left(CN\right)}_6\right]}^{3-}and{\left[Ti{\left(CN\right)}_6\right]}^{3-}$ ${{}_{}}^{}{{}_{}}^{}$ are paramagnetic.
