Question

This item is intended to allow you to practice using conventions specific to mechanisms. Try different curved arrows and click any links to view the structures predicted by the system. In this problem, you will not be penalized for incorrect answers, provided that you complete the problem either by submitting a correct answer or by exhausting all attempts. Part A Draw the important resonance contributors for the sigma complex shown here: Draw electron-flow arrows on the structure in the previous box to indicate how the electrons reorganize to give the structure in the next box. Draw all missing reactants and/or products in the appropriate boxes by placing atoms on the canvas and connecting them with bonds. Add charges where needed. Electron-flow arrows should start on the electron(s) of an atom or a bond and should end on an atom, bond, or location where a new bond should be created.
