Questions Using the spectrum attached to this procedure, assign the peaks in the 'H NMR spectrum for 3.4-methylenedioxynitrostyrene. Using coupling constants, describe the geometry of the double bond. You should tear out the labeled proton spectrum and turn it in with your notebook pages.

1. How can you use 1H NMR to distinguish between isopropyl ethanoate and methyl 2-methylpropanoate (also called ethyl isobutyate)? Isopropyl ethanoate 2. This spectrum contains two peaks that are shifted ~3 or more ppm downfield of the other three peaks.
