The most stable complex among the following is (a) K3[Al(C2O4)3] (b) [Pt(en)2]Cl2

Question

The most stable complex among the following is

(a) \(\mathrm{K}_{3}\left[\mathrm{Al}\left(\mathrm{C}_{2} \mathrm{O}_{4}\right)_{3}\right]\)

(b) \(\left[\mathrm{Pt}(e n)_{2}\right] \mathrm{Cl}_{2}\)

(c) \(\left[\mathrm{Ag}\left(\mathrm{NH}_{3}\right)_{2}\right] \mathrm{Cl}\)

(d) \(\mathrm{K}_{2}[\mathrm{Ni}(E D T A)]\)

Answer 1

Correct option is (d) \(\mathrm{K}_{2}[\mathrm{Ni}(E D T A)]\)

K₂[Ni(EDTA)] contains the maximum number of rings, i.e., five and hence is most stable.
