Yоu’ve recently cаrried оut аn extensive extrаctiоn process (fractionation) to isolate a new natural product from the leaves of the rare Sailfishius palmbeachifloridus found on the PBAU campus. The activity table for your experiment is shown here: pH2 solvent pH2 aqueous pH9 solvent pH 9 aqueous + - + - Based on this information, answer the following questions: *** a) since the compound is not found in aqueous layers, the compound is: [blank2] *** b) the UN-IONIZED form(s) of the compound are found in which layer(s)? [blank3] *** c) the unknown compound can be classified as: [blank4] *** d) You want to make sure your assay is working, so you repeat the same experiment using a laboratory standard shown below. Complete the table below (e.g. enter symbols, "+" or "-") to predict what layer(s) the standard is likely to be found in using the same extraction process. pH2 solvent pH2 aqueous pH9 solvent pH 9 aqueous [blank5] [blank6] [blank7] [blank8]
