During the chromatography the solvent may be changed from hexanes/ ethyl acetate (8:2) to hexanes/ ethyl acetate (4:6) depending on which ferrocenes are present in the mixture. What is the reason for doing this? Which of these solvent mixtures is more polar? How would you prepare 200 mL of hexanes/ ethyl acetate (8:2)?
