NMR SPECTROSCOPY Although a monosubstituted benzene ring has three different types of hydrogens, their chemical shifts are so close, that they frequently appear as a single peak. A 1,4-disubstituted benzene ring in which the two substituents are different has a characteristic pattern of aromatic hydrogen absorption. What would you predict this pattern to be? (Hint – There are two different kinds of hydrogens.)
