$[CoF_6]^{3-}$ is an outer orbital complex while $[Co(NH_3)_6]^{3+}$ is an inner orbital complex.

Vedclass · Answer

(D) In $[CoF_6]^{3-}$,the oxidation state of $Co$ is $+3$ $(3d^6)$. $F^-$ is a weak field ligand,so it forms an outer orbital complex $(sp^3d^2)$ which is paramagnetic.In $[Co(NH_3)_6]^{3+}$,the oxidation state of $Co$ is $+3$ $(3d^6)$. $NH_3$ is a strong field ligand,so it causes pairing of electrons,forming an inner orbital complex $(d^2sp^3)$ which is diamagnetic.Therefore,the statement that $[CoF_6]^{3-}$ is an outer orbital complex and $[Co(NH_3)_6]^{3+}$ is an inner orbital complex is correct.
