You perform a thin-layer chromatography test on pigments extracted from a purple flower. There are three spots, a red spot with an Rf of 0.32, a blue/purple spot with an Rf of 0.57, and an orange spot with an Rf of 0.97. Explain the intermolecular forces these pigments are likely to have those placements on the TLC plate.
