Solution: The carbocation shown below belongs to a class of intermediates known as benzyl cations. a. Draw all major resonance structures expected for this carbocation. Be sure to use proper curved arrow notation when showing the interconversion of resonance forms. b. Redraw the most important resonance contributor, if one exists. If no single resonance structure is more important than the others, simply write “ALL EQUIVALENT” in the box. c. Provide a BRIEF reason for your answer in b. Leave this blank if you wrote “ALL EQUIVALENT” for b.

Problem

The carbocation shown below belongs to a class of intermediates known as benzyl cations.

a. Draw all major resonance structures expected for this carbocation. Be sure to use proper curved arrow notation when showing the interconversion of resonance forms.
b. Redraw the most important resonance contributor, if one exists. If no single resonance structure is more important than the others, simply write “ALL EQUIVALENT” in the box.
c. Provide a BRIEF reason for your answer in b. Leave this blank if you wrote “ALL EQUIVALENT” for b.
