How many different sets of equivalent aromatic (benzene ring) carbons can be seen in the 13C NMR spectrum of your unknown monosubstituted benzene starting material? A. Are there any peaks for non-aromatic carbons in the 13C NMR spectrum of your unknown monosubstituted benzene starting material (yes or no)? B. If yes for part A, please list the corresponding ppm value(s) for any non-aromatic carbon(s)?
