Vedclass · Answer

(D) In both complexes,the central metal ion is $Co^{3+}$,which has a $d^6$ electronic configuration.For $[CoF_6]^{3-}$,$F^-$ is a weak field ligand,so it forms an outer orbital complex ($sp^3d^2$ hybridization) with $4$ unpaired electrons,making it paramagnetic.For $[Co(NH_3)_6]^{3+}$,$NH_3$ is a strong field ligand,so it causes pairing of electrons,forming an inner orbital complex ($d^2sp^3$ hybridization) with $0$ unpaired electrons,making it 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.
