Homework Answers
in this structure, four unique type of H are there.
Ha: 3H, triplet as adjacent carbon contains two H.
so three peaks.
Hb: its have sextet that is six peaks.
Hc : it shows triplet. that is three peaks. assuming -OH proton is exchangeable with solvent.
Hd : singlet. one peak.
if OH proton is not exchangeable then Hc shows four peaks and Hd shows triplet that is three peaks.

splitting patterns lastly let’s discuss
Splitting Patterns Lastly, let's discuss why some signals are comprised of only a single peak, called a singlet, while other signals exhibit splitting, and may appear as a doublet, triplet, quartet, quintet, sextet, septet, octet, nonet, etc. Splitting is due to neighboring H's. That is, H's that are separated by 3 covalent bonds are called "neighbors". Each neighbor splits a signal, and the pattern observed matches the N+1 rule: the number of peaks observed is...

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...
