Human white cells produce an enzyme called myeloperoxidase. This enzyme catalyzes the reaction between hydrogen peroxide and chloride ion to produce hypochlorous acid, HOCI, which reacts as if it were Cl*OH . When attacked by white cells, choles- terol gives a chlorohydrin as the major product. Me Me R white blood cells Me R Me | OH/ НО HO- CI Cholesterol Cholesterol chlorohydrin

Propose a mechanism for the following reactions.

The reaction of butan-2-ol with concentrated aqueous HBr goes with partial racemization, giving more inversion than retention of configuration. Propose a mechanism that accounts for racemization with excess inversion

odine monochloride, ICI, is a reagent whose reactivity mirrors that of other dihalogens (X₂) with nucleophilic πt bonds. Using curved arrows to show the flow of electrons, draw a plausible mechanism for the following transformation. Make sure that your mechanism accounts for the correct stereoselectivity.
