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...
