MCQ
From the stability constant (hypothetical values), given below, predict which is the strongest ligand :
- A$Cu^{2+} + 4NH_3 \rightleftharpoons [Cu(NH_3)_4]^{2+} \,\,\,,$ $K = 4.5 \times 10^{11}$
- ✓$Cu^{2+} +4CN^- \rightleftharpoons [Cu(CN)_4]^{2-} \,\,\,,$ $K = 2.0 \times 10^{27}$
- C$Cu^{2+} + 2en \rightleftharpoons [Cu(en)_2]^{2+} \,\,\,,$ $K = 3.0 \times 10^{15}$
- D$Cu^{2+} + 4H_2O \rightleftharpoons [Cu(H_2O)_4]^{2+} \,\,\,,$ $K = 9.5 \times 10^8$
