.CH3 р-Хylene H3C

How many peaks would you expect in the ¹H NMR spectrum of 1,4-dimethyl- benzene (para-xylene, or p-xylene)? What ratio of peak areas would you expect on integration of the spectrum? Refer to Table 13-3 for approximate chemical shifts, and sketch what the spectrum would look like. (Remember from Section 2-4 that aromatic rings have two resonance forms.)
