BackLook closely at the resonance structures of the benzylic anions, radicals, and cations in Figures 24.2–24.4. On which benzene carbons did the charge/radical exist in the resonance structures—that is, were they ortho, meta, or para?
Which has the greater delocalization energy?
List the following in order of decreasing delocalization energy:
