NMR Spectroscopy of Aromatic Compounds (#1e)

40 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 …
