Question

Write the hybridization and number of unpaired $e^{-}$ in the complex $[C o F e]^{3 -}$ .

Open in App

Solution

Hybridization in the complex $[C o F_{6}]^{3 -}$ is $s p^{3} d^{2}$ because fluorine is a weak field ligand.
The number of unpaired electrons is 4.
The electronic configuration of Co is $[A r] 4 s^{0} 3 d^{6}$ .
