The enantiomeric iron complexes synthesized in the experiment have no obvious differences in physical properties. They are the same color, have the same solubility in water, the same melting point and boiling point, etc. This phenomenon is completely general for enantiomers.
Why are the physical properties of enantiomers identical? (Note that diastereomers have different physical properties.)
