What is chelating ligand ?

Text Solution

Verified by Experts

Ligands resulting in close ring structures with the metal ions are called chelating ligands. Ethane 1,2-diamine is involved in the formation of a cyclic ring with Cu (II)ion

Which of the following are chelating ligands? H_(2)O C_(2)O_(4)^(2_) , EDTA^(4-) , CO_(3)^(2-) , SCN^(-) , CO, C_(2)H_(4)

Consider the two complexation equilibria in aqueous solution, between the cobalt (II) ion Co^(2+) (aq) and ethylenediamine (en) on the one hand and ammonia NH_(3) on the other. [Co(H_(2)O)_(6)]^(2+)+6NH_(3)hArr[Co(NH_(3))_(6)]^(2+)+6H_(2)O ...(1) [Co(H_(2)O_(6))]^(2+)+3enhArr[Co(en)_(3)]^(2+)+6H_(2)O ..(2) Electronicaly, the ammonia and en ligands are very similar, since both bond through N and since the liwis base strengths of their nitrogen atoms are similar. This means that DeltaH^(@) must be very similar for the two reactions, since six Co-N bonds are formed in each case. Interestingly however, the equilibrium constant is 100,000 times larger for the second reaction than it is for the first. This is the so called chelate effect: "the enhanced affinity of chelating ligands for a metal ion compared to similar non-chelating (monodentate) ligands for the same metal". The chelate effect is entropy-driven. Q. Which of the following can be classified as a chelating ligand?

Explain with examples what is meant by chelate ligands ?

Assertion (A) Toxic metal ions are removed by the chelating ligands. Reason (R) Chelate complexes tend to be more stable.
