Draw the mechanism for the anti-Markovnikov hydrobromination of 3-methylbut-1-ene. Draw all five steps in the mechanism, one step per line. Be sure to show the fishhook curved arrows for each step, and the radical intermediates that are produced. Steps one and two are initiation steps. Steps three and 4 are propagation steps. Step five is termination. Also, identify each step as homolytic cleavage, coupling, addition to a pi bond, elimination, hydrogen abstraction, or halogen abstraction. Finally, show how the two propagation steps sum to give the overall reaction.
