What is the order of strong to weak field ligands

Accepted Answer

The spectrochemical series, which arranges ligands from strong to weak field, is: CO > CN- > NO2- > en > NH3 > H2O > OH- > F- > Cl- > Br- > I-. This order is based on how strongly the ligands interact with the metal ion's d orbitals, influencing the splitting of d orbitals in coordination complexes.
