Which of the following compounds has electrons symmetrically distributed in both t _ 2 ~g and eg orbitals?

Step-by-step solution

The electronic configuration of the central metal ion in each complex is determined as follows: For [ CoF ₆ ]³⁻ , the oxidation state of Co is +3 . The configuration of Co ³⁺ is 3d^6 . Since F ⁻ is a weak field ligand, the configuration is t_ 2g ^4 e_g^2 . The distribution is not symmetric. For [ FeCl ₆ ]³⁻ , the oxidation state of Fe is +3 . The configuration of Fe ³⁺ is 3d^5 . Since Cl ⁻ is a weak field ligand, the configuration is t_ 2g ^3 e_g^2 . The distribution is symmetric as t_ 2g is half-filled ( 3 electro
