Three pigment solutions are given to you. The first pigment, A, contains four -OH and two -NH groups. The second pigment, B, has two-OH groups. The third pigment, C, has a very long hydrocarbon chain with no oxygen. You are told to separate these pigments by paper chromatography using a solvent composed of 70% benzene and 30% acetone. Predict the locations of the three pigments on the paper with respect to the solvent front after they separate. Explain your answer.
