Arrange the following ligands in order of increasing field strength, from weakest to strongest.

Options

  1. ACl– < CO < NCS– < F– < OH– < edta4– < S2– < I–
  2. BI– < S2– < edta4– < OH– < F– < NCS– < CO < Cl–
  3. CCl– < S2– < edta4– < F– < NCS– < OH– < CO < I–
  4. DI– < edta4– < CO < S2– < OH– < NCS– < F– < Cl–

Correct answer

B. I– < S2– < edta4– < OH– < F– < NCS– < CO < Cl–

Step-by-step solution

The correct order of increasing field strength is I– < S2– < edta4– < OH– < F– < NCS– < CO < Cl–
