Draw the expected H NMR spectrum for each molecule. Pay
attention to the chemical shift and splitting. Mark the integration
of each peak. Then assign each peak in the NMR to hydrogen atoms in
the structure.

PART 2 Draw the most accurate 'H-NMR spectrum you can for the following molecules. Show all signals including an accurate representation of splitting, intensity and position. Assume no signal overlap (i.e. if you expect signals have similar chemical shifts, just place them next to each other). Clearly label the integration value for each signal.
