8. a) AIBN (the initial structure below) is a different initiator that is often used for free-radical reaction processes. The following sequence illustrates its decomposition to form a radical, followed by initiation of styrene polymerization. Draw the mechanism (curvy arrows) for both steps of this sequence. [7 pts) CH3 2 N= H3C CH3 H3C CH3 + NEN 9. Explain why the product of the initiator with the styrene monomer is the structure shown in the box rather than the alternate structure? Be specific about the most significant structural cause (what specific atoms involved in steric effect, what specific type of electronic effect, etc.) with proper terminology, rather than simply naming the nature of the structure. [3 pts] NOT In In
