How did the chemical structures of the analyte relate to the Rf values, mobile phase and stationary phase? Were the Rf values in consistent with the chemical structures of acetaminophen, aspirin, and caffeine?

The analytes were acetaminophen, aspirin, and caffeine, and the Rf values from highest to lowest was: acetaminophen > aspirin > caffeine, which means polarity increased from acetaminophen < aspirin < caffeine
