Two propagation steps are given below. (a) Draw the intermediate compound in the Step 2 box. (Keep Br2.) (b) Draw the appropriate curved arrows - in the Step 1 and 2 boxes - to show the mechanism of each step. See the Hint for formatting procedure..
Explain the factors that affect rate and relative reactivity. Use a mechanism(s) and reactions to support your claims.
