This can be explained by the fact that Ibuprofin has the least interactions by having only one weak dipole-dipole bond and one strong hydrogen bond. Phenacetin has the second highest R F because it contains.National Cancer Institute () Bioassay of mixture of aspirin, phenacetin, and caffeine for possible carcinogenicity.
