2. Aspirin, acetaminophen, and caffeine are some of the substances being tested in this TLC experiment. Look at their structures and atoms present to help you explain why 100% hexane would NOT be a good TLC developing solvent (chromatography solvent) to use in this Thin Layer Chromatography experiment.

Extra-strength Excedrin is a combination of 250 mg acetaminophen 250 mg aspirin, and 65 mg caffeine plus inactive ingredients that are insoluble in water and organic solvents. Using the data in Table E9.1. draw a flowchart to show how these three components could be sepa- rated using their solubility and acid-base properties. Hint: Caffeine is a nitrogen base similar in reactivity to diisobutylamine (Section 7.6.1 and Experiments 2 and 7). HN OH NN OH acetaminophen aspirin caffeine

1. Propose a synthesis for aspirin, Ibuprofen and acetaminophen. Start with benzene and any other reagents that contain 4 or less carbons. 2. What error is introduced into the determination of an Rf value if the solvent front migrates to the top of the TLC plate? 3. Why is the TLC run in a closed chamber?

You are asked to analyze the following two solutions: Solution 1 – acetaminophen, ibuprofen, and aspirin Solution 2 – methyl t-butyl ether, isooctane and n-butanol (gasoline additives) Explain which chromatographic technique (GC or HPLC) you would use to separate each of these mixtures and why that technique would be useful for that separation. Indicate columns and detectors when appropriate.

2. While caffeine is very soluble in water, aspirin is only minimally soluble. a. Clearly explain why you think caffeine is soluble in water. b. In order to dissolve the aspirin, I had to use a sodium hydroxide solution (this is why you had to add HCl to the separatory funnel.) Clearly explain how the use of a sodium hydroxide solution allowed the aspirin to dissolve. Structures/reaction(s) will likely help your answer.
