Vedclass · Answer

(A) The magnitude of crystal field splitting energy $\Delta_0$ is directly proportional to the field strength of the ligand.According to the spectrochemical series,the order of field strength of the given ligands is: $CN^- > NH_3 > C_2O_4^{2-} > H_2O$.Since $CN^-$ is the strongest field ligand among the options,the complex $[Co(CN)_6]^{3-}$ will have the highest $\Delta_0$ value.

For an octahedral complex of $Co$ $(Z = 27)$,which of the following has the highest value of $\Delta_0$?
