Get started for freeQuestion: Resveratrol is an antioxidant found in the skin of red grapes. Its anticancer, anti-inflammatory,and various cardiovascular effects are under active investigation. (a) Draw all resonancestructures for the radical that results from homolysis of the OH bond shown in red. (b) Explainwhy homolysis of this OH bond is preferred to homolysis of either OH bond in the otherbenzene ring.
Question: Which C-H bond is most readily cleaved in linoleic acid? Draw all possible resonance structures for the resulting radical. Draw all the hydroperoxides formed by the reaction of this resonance stabilized radical with O2.

Question: As described in Section 9.16, the leukotrienes, important components in the asthmatic response, are synthesized from arachidonic acid via the hydroperoxide 5-HPETE. Write a stepwise mechanism for the conversion of arachidonic acid to 5-HPETE with O2 .
Question: In the presence of a radical initiator (Z* ), tributyltin hydride ( R3SnH,R=CH3CH2CH2CH2 ) reduces alkyl halides to alkanes: R'X+R3SnHR'H+R3SnX. The mechanism consists of a radical chain process with an intermediate tin radical:
This reaction has been employed in many radical cyclization reactions. Draw a stepwise mechanism for the following reaction.
