3. Enones and Aromatic systems are nice in that their absorption maxima can usually be well predicted using simple tables. Based on the tables in the text, predict the absorption maxima for the following compounds. Show your work and not just a final number for full credit. 4. Concentration determinations are a very important application of UV/Vis spectroscopy and are based on the use of the Beer-Lambert law. Using the given data, calculate the concentration of the given compound and then calculate the predicted absorption values for the specified diluted solutions. Morphine hydrochloride features an absorption maximum at 285nm and a molar absorptivity of 1,540L/molcm in water. If an unknown solution in water gives an absorption of 980 , what is the concentration of this solution? If you then take 1mL of this solution and dilute it with 9mL. of water, what absorption value would you expect to see? Quinine sulfate features an absorption maximum at 348nm and a molar absorptivity of 5,700 U/mol cm in water. If an uniknown solution in water gives an absorption of 4,500 , what is the concentration of this solution? If you then take 0.5mL of this solution and dilute it with 9.5mL. of water, what absorption value would you expect to see
