Unformatted text preview: structures drawn below? ? a) b) c) d) e) Comments: This question was about understanding resonance, and not confusing it with carbocation rearrangements. The structures differ only in position of π electrons (which by definition is resonance). None of the atoms change position (which would be required in a carbocation rearrangement). There was no direct precedent for this question, but it tests a very basic concept. All questions on 1,2- vs. 1,4- electrophilic addition require understanding of that concept....
