www.unm.edu40 13C NMR Spectroscopy of Aromatic Compounds As with other 13C NMR spectra, aromatic compounds display single lines for each unique carbon environment in a benzene ring. Aromatic carbons appear between 120-170 ppm. The 13C NMR spectra of bromobenzene and p-bromoethylbenzene are shown below for comparison.There are four different carbon environments in bromobenzene, and four …

www.saplinglearning.com1226 CHAPTER 25 • THE CHEMISTRY OF THE AROMATIC HETEROCYCLES B. Acidity of Pyrrole and Indole Pyrrole and indole are weak acids. With p K a values of about 17.5, pyrrole and indole are about as acidic as alcohols and about 15–17 pK a units more acidic than primary and secondary amines (Sec. 23.5D). The greater acidity of pyrroles and indoles is a consequence of the resonance stabilization ...
