SUMMARY
The discussion centers on the Rf values of acetaminophen and phenacetin during TLC chromatography using silica gel and a nonpolar solvent. Acetaminophen exhibits a higher Rf value due to its phenolic group, which makes it less polar compared to phenacetin, which contains an aromatic ether. The polarity of the compounds significantly influences their separation on the TLC plate, with acetaminophen being less polar and thus traveling further in the nonpolar solvent.
