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

1. SCN- < F- < CN- < C2O4 2-
2. F- < SCN- < C2O4 2- < CN-
3. CN- < C2O4 2- < SCN- < F-
4. SCN- < F- < C2O4 2- < CN-

Correct answer: SCN- < F- < C2O4 2- < CN-

Solution

The correct order is based on the spectrochemical series, which ranks ligands by their field strength. CN- is the strongest ligand, followed by C2O4 2-, F-, and SCN-.
