What can you say about how Norbixin and Beta Carotene will behave in your experiment just by looking at the circled differences in their structures? ( the experiment was thin Layer Chromatography. finding compounds in spinach juice using their polarity and retention factor, Rf= distance traveled by the compound / distance traveled by the solvent). (Please do not copy and past some idea from other websites. I can do that myself) undefined
