You are trying to determine a TLC solvent system which will separate the compounds $$X,Y$$, and $$Z$$. You ran the compounds on a TLC plate using hexanes/ethyl acetate $$80:20$$ as the eluting solvent and obtained the chromatogram below. Based on this data, what solvent system could you use to give a better separation of these three compounds? Elute with 70:30 hexanes/ethyl acetate Elute with $$100\%$$ ethyl acetate Elute with $$100\%$$ hexane Elute with $$90:10$$ hexanes/ethyl acetate
