Question

Write an arrow formalism mechanism for the following reaction. Explain why 1 is formed, but 2 is not. Он Н,о Н.о OH Be sure to give us two reasons why the OH winds up adjacent to the ring and not on the other carbon of the starting allkene. он H3O* Н.о 2

Answer 1

Date: Page: KI He will not attack to the aromatic ring because molecule. will be unstable so it will attack on other IT-bond. . less stable Reason-2° Carbocation & No resonance this intermediate is more stable because it is tertiary Carbocation and Resonance stablised- so oH goes to - adjecent site of

I attack of H₂O can be from seep the plane or down the plane.) Ho pour OH ajor) (menos)

Product one is major because it has least steric repulsion because phenyl ring is away from bridge hydrogen. Ille on Н . Less repulsion more stered repulsion
