Vedclass · Answer

(D) The central metal ion is $Co^{3+}$,which has an electronic configuration of $[Ar] 3d^6$.$F^-$ is a weak field ligand,so it does not cause pairing of electrons in the $3d$ orbitals.Therefore,the complex uses the outer $4d$ orbitals for hybridisation.For a coordination number of $6$,the hybridisation is $sp^3d^2$,resulting in an outer orbital high-spin complex.

The hybridisation involved in $[CoF_6]^{3-}$ is :
