REVIEW Topics [References) CH HC OCH Br2 CH3 B H3C CH,OH H₂C CH₂ Electrophilic addition of hypohalous acids to alkenes yields a 1,2-haloalcohol called a halohydrin. Halohydrin formation, however, does not result from the addition of HOBr, for example. Instead the addition is done indirectly by reaction of the alkene with Br, in the presence of water. The reaction also works with Cl2 to give chlorohydrins instead of bromohydrins. The reaction proceeds through a cyclic intermediate known as...
