1.	Among the following, the most stable complex is (i). `[Fe(H_2O)_6]^(3+)` (ii). `[Fe(NH_3)_6]^(3+)` (iii). `[Fe(C_2O_4)_3]^(3-)` (iv). `[FeCl_6]^(3-)`
Answer» In each of the given complex Fe is in +3 oxidation state As `C_(2)O_(4)^(2-)` is didentate chelating ligand it forms chelate rings and hence (iii) out of complexes given above is the most stable complex.
