Aromatic Compounds

Ch16 Aromatic Compounds (landscape).docx Page 4 Unusual Behavior of Benzene Benzene has much more stability than predicted by the simple resonance delocalized structure. For example, we know alkenes can be oxidized to syn diols (KMnO 4) and undergo electrophilic additions with halogens (Br 2). Yet the same reactions do not work with benzene.

toward electrophilic aromatic substitution, and that the methyl group is an activating group). 2) Nitration of toluene generates a mixture of products. The major products are those with substitution at the ortho and para positions. (This preference for o/p substitution makes the methyl group an ortho/para director).
