Vedclass · Answer

(C) The stability of a coordination complex is significantly enhanced by the chelate effect. Among the given options,$[Fe(C_2O_4)_3]^{3-}$ contains the oxalate ion $(C_2O_4^{2-})$,which is a bidentate ligand. This ligand forms five-membered chelate rings with the central metal ion,leading to increased thermodynamic stability compared to complexes with monodentate ligands like $H_2O$,$CN^-$,or $Cl^-$. Therefore,$[Fe(C_2O_4)_3]^{3-}$ is the most stable complex.
