The only incorrect order of CFSE values of the given id [ Ni ( DMG )2]<[ Ni ( en )2]2+.

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

$[C r (N O_{2})_{6}]^{3 -} > [C r (N H_{3})_{6}]^{3 +} > [C r (H_{2} O)_{6}]^{3 +}$

$[Pt F_{4}]^{2 -} > [P d F_{4}]^{2 -} > [N i F_{4}]^{2 -}$

$[N i (D MG)_{2}] < [N i (e n)_{2}]^{2 +}$

[Co(EDTA)] $^{-} > [C o (e n)_{3}]^{3 +}$

The only incorrect order of CFSE values of the given id $[N i (D MG)_{2}] < [N i (e n)_{2}]^{2 +}$ .
