Which of the following is the correct order of increasing field strength of ligands to form coordination compounds?

A$$SCN^- < F^- < CN^- < C_2O^{2-}_4$$
B$$F^- < SCN^- < C_2O_4^{2-} < CN^-$$
C$$CN^- < C_2O_4^{2-} < SCN^- < F^-$$
D$$SCN^- < F^- < C_2O_4^{2-} < CN^-$$
Correct Answer

Solution

In general, ligands can be arranged in a series in the order of increasing field strength as given below:

$$I^- < Br^- < SCN^- < Cl^- < S^{2-} < F^- < OH^- < C_2O_4^{2-} < H_2O < NCS^- < EDTA^{4-} < NH_3 < en < $$

$$CN^- < CO$$

Option D is correct.
