The normal chemical shift of a proton in benzene and compare to the chemical shifts in Entry 4 of Table 16-5 and find the source of those differences in chemical shift. Concept introduction: If protons are adjacent or near to a carbon having an electron-withdrawing group, then they get deshielded and cause a downfield shift. Benzene and additional oxygen atoms also can cause such deshielding.
