Vedclass · Answer

(C) In $[CoF_6]^{3-}$,the oxidation state of $Co$ is $+3$. The electronic configuration of $Co^{3+}$ is $[Ar] 3d^6$. Since $F^-$ is a weak field ligand,it does not cause pairing of electrons in the $3d$ orbitals. Therefore,the $4s$,$4p$,and $4d$ orbitals are used to form $sp^3d^2$ hybrid orbitals. Thus,$[CoF_6]^{3-}$ is an outer orbital complex with $sp^3d^2$ hybridization.

$[CoF_6]^{3-}$ is formed by $...$ hybridization.
