h most polare compounds that you observed in your drug mixture in the space below. Rank them polar. Finally, explain why each compound is more or less polar than other components. 4. Draw the to least MOST POLAR LEAST POLAR Explanation: 5. The identity of your unknown drug can be found by analyzing the components in your mixture. What unknown drug did you chromatograph, and briefly, how did you arrive at this conclusion? 6. What would happen if you carried out a TLC separation of acetaminophen and phenacetin in a normal phase and reverse phase TLC system? Explain which should have a higher Rf value for each type of chromatography and explain why 7. Describe the effects on your experimental outcomes from the following situations: I) You allowed the TLC to develop too long and the solvent ran off the plate. 2) The TA helping with lab used ammonia instead of acetic acid in your developing solvent. 3) You marked the starting line with a ballpoint pen. 1) 2) 3)
