(Review Topics 1. Hg(OAC)2, H20 2. NaBH, . H2O OH CHI CH3 H3C H3C Hoc Acid-catalyzed addition of water to an alkene yields an alcohol with Markovnikov repiochemistry. The electrophilic adds to the sp? carbon with the most hydrogens to yield the most stable carbocation intermediate, which then adds water to give the product alcohol Because a carbocation intermediate is formed, rearrangements can occur prior to the addition of water To avoid the possibility of rearrangement and still give a...
