Polar
Phenacetin will have a higher Rf value than acetaminophen in a TLC separation on silica gel using a non-polar developing solvent. This is because phenacetin is more non-polar than acetaminophen, causing it to move further up the TLC plate and have a higher Rf value.
Caffeine > Acetaminophen > Ibuprofen > ASA Actually ASA is more polar than Ibuprofen. In ethanol ASA rf value is around .7 and Ibuprofen is around .77. Should be Caffeine > Acetaminophen > ASA > Ibuprofen Rf in ethanol Caffeine < Acetaminophen < ASA < Ibuprofen
Nonpolar
It is non-polar
Polar molecules reacts with polar molecules and non-polar molecules react with non-polar molecules.
Acetaminophen will have Rf value of about 0.4 and ibuprofen will have Rf value of about 0.6 if the non polar solvent used is ethanol.
From most polar to least:Caffeine, Acetaminophen, Aspirin
