a. Both the reactant and product show very similar IR spectra. For the reactant, indicate which IR
signals are due to the presence of the amide group? Specifically, which signal is due the NH
stretch (indicate which signal is due to the "free" NH stretching vibration and which signal is due
to the "hydrogen bonded" NH stretching vibration?
You may either type your answers below or write your answers on the given spectrum
shown above.
