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. Indicate the correlation between each proton (HA, HB, etc) and each signal (label signals A, B, etc.) ppm 12.5 10 11 O ppm 12.5 10 ii...

II. Number of Signals 2. Predict the number of unique protons that would generate peaks in an NMR spectrum. Look at Figure 13.6 and example problem 13.2 for guidance. Then for each of these unique proton signals, predict the ppm range where you would find it and the integration value or signal area. Look at figure 13.7 in your textbook. Finally, determine the splitting pattern (multiplicity) of the signal. This is predicted using the n+1 rule. Watch the video for...
