Why is the order of polarity like this: Caffeine(most polar)>Acetaminophen>Aspirin I thought that the order should have been the opposite because aspirin has 4 … Inspection of the structures of aspirin and caffeine reveals that they are organic acid and organic base, respectively. The key to determining if something is polar or not is by determining if it is water soluble. I think that the caffiene would be the most polar, as it is more attracted to the stationary phase (which is also polar) and not so much the mobile phase (which is non-polar). A percent recovery was calculated to see Ho 1 Whether the molecule behaves more like a polar or non-polar molecule will depend on which region is more significant. I understand the the most polar molecules non-polar will bind to the column so would the Aspirin is said to be the least polar, having travelled the greatest distance due to its high affinity to the slightly polar solvent.
