Using arrows to show the flow of electrons in elementary steps in the reaction mechanism for the reaction shown below, give one initiation step, two propagation steps, three radical-radical combination termination steps, and one disproportionation termination step. You do not need to give more than one Lewis structure (resonance structure) for any reactive intermediates. If a product is present as a mixture of enantiomers or diastereomers, show using lines, wedges, or dashed wedges. Label each step as "initiation", “propagation”, or “termination”.
