Question

For each problem, you must:
1) Calculate the degree of unsaturation.
2) Assign the principal IR absorption bands above 1500 cm -1
3) Draw the structure of the compound
4) Label the protons on your structure with letters and assign them to peaks on the NMR spectrum
(see the example below)

Each problem contains the formula of the compound, the IR spectrum (with axes in cm³¹ vs. %
transmission), and the ¹H NMR spectrum (with axis in PPM shift). Some NMR spectra show a peak
hovering above the baseline. This is a magnified view of one of the actual peaks, to allow you to see
splitting more clearly.
