5) Assign the peaks in the 'H NMR spectrum of your product. Draw your structure on the NMR spectrum and label each set of inequivalent protons. Use these labels in assigning the peaks. In some cases the aromatic peaks may overlap, so it is OK to assign groups of protons to a series of overlapping peaks if necessary. Try to be as specific as possible in your assignment, though. Discuss in detail how the NMR spectrum is only consistent with...

With the values of the possible products. 4) Discuss the IR spectra of your starting materials. Based on your spectra determine which unknown was the aldehyde and which was the ketone. You should discuss the key peaks you used to make these assignments. If your IR spectra were helpful in identifying which ketone or aldehyde you had, discuss this as well. For additional info, see the IR modes handout on the class web site. 5) Assign the peaks in the...
