Vedclass · Answer

(C) The stability of coordination complexes is significantly influenced by the chelate effect. Chelating ligands form ring structures with the central metal ion,which increases the stability of the complex compared to complexes with monodentate ligands. In the given options,$[Fe(C_2O_4)_3]^{3-}$ contains oxalate ions $(C_2O_4^{2-})$,which are bidentate ligands that form stable five-membered chelate rings with the $Fe^{3+}$ ion. Therefore,$[Fe(C_2O_4)_3]^{3-}$ is the most stable complex among the choices.

Which of the following complexes is the most stable: $[Fe(H_2O)_6]^{3+}$,$[Fe(CN)_6]^{3-}$,$[Fe(C_2O_4)_3]^{3-}$,or $[FeCl_6]^{3-}$?
