Which statement about Markovnikov's rule is correct? Radical addition of HBr to an alkene produces a Markovnikov product. Markovnikov's rule dictates that the more stable alkene is the major product. Addition of water to alkenes via hydroboration-oxidation produces a Markovnikov product. O Markovnikov's rule is a consequence of carbocation intermediate stability. Markovnikov's rule dictates that hydrogen is attracted to the side of the alkene with more hydrogens through intramolecular forces.
