From the 13C spectrum of a compound, one can assign signals to specific carbon atoms of the compound and determine the number of protons on each of those carbon atoms. Such information in conjunction with the DEPT C-13 chart will allow the appearance of the corresponding DEPT spectrum of the compound to be predicted. There are five signals (I – V) in the 13C spectrum of compound A as shown below. At the exactly same location of each of these five signals, "a peak", "no peak", or "an inverted peak" may appear in the corresponding DEPT-135 spectrum. Predict the DEPT-135 spectrum of compound A by selecting the expected signal appearance at each of these five locations in the DEPT-135 spectrum. - II II IV V in HO A 100 PPM 180 160 140 120 80 60 40 20 v At the location of signal I A. no peak v At the location of signal IIl В. а рeak v At the location of signal IIl C. an inverted peak v At the location of signal IV v A the location of signal V

The 1H-NMR spectrum of 1-chloropropane shows three signals and the 1H-NMR spectrum of 2-chloropropane shows two signals. Draw these two molecules and determine the relative integrals of each signal.

4) Draw the compound with molecular formula C9H100 that produces the following signals. Show your work by labeling your structure (Ha, Hb, etc.): 1H NMR a) 9.8 ppm, singlet, 1 H b) 7.3-7.6 ppm, multiplet (overlapping signals), 5 H c) 3.2 ppm, triplet, 2 H d) 2.8 ppm, triplet, 2H 13C NMR: 201.5, 140.7, 128.6, 128.5, 126.4, 45.2, 25.1 ppm
