    Experiment 10 Thin Layer Chromatography Purpose! To identify how many components are in a mixture and the identity of a compound in a mixture by comparing the Rf of a known compound with the Rf of an unknown compound. Intodection. In this experiment the thin-layer chromatography the (TLC) will be used to determine the composition of various over-the-counter analgesic. We will be given two commercially prepared TLC plates with a flexible backing and a silica-gel coating with a fluorescent

    Stereochemistry of Dihydroxylation Reactions Question: Can the stereochemical outcome of dihydroxylation reactions be determined by thin layer chromatography? Overview: In this experiment‚ you will perform two reactions that transform alkenes into diols. While similar in functional group transformation‚ these reactions may lead to stereochemically different products. The two possible products are diastereomers of one another‚ and therefore have different physical chracteristics. After
