Question

This is the H NMR spectrum for the product of a reaction between either benzaldehyde, 4-methybenzaldehyde, 4-methoxybenzaldehyde, or cinnamaldehyde with either acetone, cyclopentanone, cyclohexanone, 4-methylcyclohexanone. Assign the peaks in the 1H NMR spectrum to this product. Hand-draw the 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 acceptable to assign multiple groups of protons to a series of overlapping peaks if necessary; nevertheless, try to be as specific as possible in your assignment.
