Which of the following options explain the chelate effect with an example?

Options

  1. AThe chelate effect refers to the increased stability and enhanced colouration observed in metal complexes when
  2. BThe chelate effect is the tendency of metal complexes to become less stable when chelating ligands are involve
  3. CThe chelate effect is a phenomenon where metal ions become completely unreactive in the presence of chelating
  4. DThe chelate effect is the change in colour of metal complexes when they react with chelating ligands. An examp

Correct answer

A. The chelate effect refers to the increased stability and enhanced colouration observed in metal complexes when

Step-by-step solution

Correct Option is : (A) The chelate effect refers to the increased stability and enhanced colouration observed in metal complexes when multidentate ligands (chelating ligands) form multiple bonds with the central metal ion. An example is the formation of [Ni[EDTA]] 2-
