NMR SPECTROSCOPY OF AROMATIC COMPOUNDS
www.unm.eduIn aromatic compounds like benzene, the protons on the aromatic ring are shifted downfield. For example, the six protons in benzene are magnetically and chemically equivalent and appear at 7.33 ppm. This is farther downfield than alkene protons, which appear between 4.5-6.5 ppm. NMR serves as a useful tool to determine whether a compound is ...
