Problem

The crystal field theory assumes interaction between metal ion and the ligands as a purely electrostatic and ligands are supposed to be point charges. Which of the following order of CFSE is incorrect ? (1) [Cr(NO2)6]3−>[Cr(NH3)6]3+>[Cr(H2O)6]3+[\text{Cr}(\text{NO}_2)_6]^{3-} > [\text{Cr}(\text{NH}_3)_6]^{3+} > [\text{Cr}(\text{H}_2\text{O})_6]^{3+} (2) [PtF4]2−>[PdF4]2−>[NiF4]2−[\text{PtF}_4]^{2-} > [\text{PdF}_4]^{2-} > [\text{NiF}_4]^{2-} (3) [Ni(DMG)2]<[Ni(en)2]2+[\text{Ni}(\text{DMG})_2] < [\text{Ni}(\text{en})_2]^{2+} (4) [Co(EDTA)]−>[Co(en)3]3+[\text{Co}(\text{EDTA})]^- > [\text{Co}(\text{en})_3]^{3+}
