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
