Answer the following question regarding the pictures please: The information for this set is based off of the column separation of ferrocene and acetylferrocene. D:What makes ethyl acetate a suitable or unsuitable solvent? ethyl acetate is too polar there would be no issues separating the three compounds using ethyl acetate as the solvent ethyl acetate is not polar enough E: What concerns would you have if you were to run a column using hexanes as the solvent for the whole column? hexanes is too polar and there would be no separation for the three compounds hexanes would be a good solvent to isolate all three compounds from the column hexanes is not polar enough to elute diacetylferrocene hexanes is not polar enough to elute any of the compounds no matter how much solvent you use F: Come up with an appropriate solvent gradient to get the best separation of all three compounds, list them first to last
