MCQ
The most stable complex among the following is
  • A
    ${K_3}[Al{({C_2}{O_4})_3}]$
  • B
    $[Pt{(en)_2}]C{l_2}$
  • C
    $Ag{(N{H_3})_2}Cl$
  • ✓
    ${K_2}(Ni(EDTA)]$
✓

Answer

Correct option: D.
${K_2}(Ni(EDTA)]$
d
$K_2[N i(E D T A)]$ is most stable as charge density for metal atom is maximum and $EDTA$ is strong ligand among all so its stablility constant and stability is maximum.
