Vedclass · Answer

(B) The $CFSE$ (Crystal Field Splitting Energy) depends on the nature of the ligand and the metal ion.For the same metal ion,the order of field strength is $en > NH_3 > H_2O$,so option $A$ is correct.For $Ni^{2+}$ complexes,$[Ni(DMG)_2]$ is a square planar complex with strong field ligands,whereas $[Ni(en)_2]^{2+}$ is tetrahedral/octahedral depending on conditions,but generally,the $CFSE$ of $[Ni(DMG)_2]$ is higher than $[Ni(en)_2]^{2+}$.Thus,the statement $[Ni(DMG)_2] < [Ni(en)_2]^{2+}$ is incorrect.

Which of the following order of $CFSE$ is incorrect?
