Create a table with the headings Proton Label,
Theoretical Chemical Shift (8 ppm), multipilicity, coupling, &
theoretical J value (Hz) for Acetylsalicylic acid using the labels
shown on the structure below. On the spectrum you made during the
lab, assign the protons by labeling the peaks on the spectrum with
the correct proton label.

In the proton NMR for benzil, there are clearly some impurity
peaks below 8 ppm. Although we cannot assign these for certain, is
it possible that these peaks come from unreacted benzoin? Why or
why not?
