Chemistry of free radicalsAlthough most textbooks in organic chemistry devote very little attention to chemistry of free radi-cals, those processes are very important in biochemistry and material science.Task1. Look up the structure of AIBN (Azobisisobutyronitrile) and explain what makes it a very goodradical initiator for laboratory applications.2. Draw the mechanism of free radical polymerization that produces tetramer of polyvinyl chlo-ride. Use AIBN (Q1) as to initiate the radical chain reaction. Use coupling of two tetramers toshow the termination step.3. Unsaturated fatty acids readily undergo radical-mediated peroxidation. Describe thegation stage of peroxidation reaction by showing peroxidation of oleic acid. Peroxidation ofarachidonic acid is 200 times faster than oleic acid. Briefly explain that observation.propa-

Show:a. the overall reaction (reactants --> products)b. the reaction mechanism (indicate intermediate product)c. indicate which is the reactive species or intermediate in the reaction (radical? electrophile? nucleophile?)d. overall description of the reaction eg., radical substitution or SR
A ketene acetal can undergo free radical ring-opening polymerization, as shown below. After the initial radical, R•, is produced, the catalytic cycle that adds each monomer to the growing chain consists of two steps. Draw the mechanism for those two steps and draw the repeating unit for the resulting polymer.
