1. Hg(OAc)2, H20 2. NaBHA CH3 M HC CHE нас Acid-catalyzed addition of water to an alkene yields an alcohol with Markovnikov regiochemistry. The electrophilic H 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 Markovnikov alcohol, alkenes can...
