Addition of HX on alkene proceed through formation of carbocation . This reaction is follows Markovnikov's rule. According to markovnikov's rule addition of electrophile occurs on that carbon of alkene which have more number of -H atom Ph-CH = CH_2 underset(HX)to underset("(major)")(Ph-overset(x)overset(|)CH-CH_3) + underset("(minor)")(Ph-CH_2-CH_2-X) Which of the following alkenes will give markovnikov's reaction ?
