To see the essence of Markovnikov’s rule from the influence of electronic effect

When alkene’s electrophilic addition reaction is judged through the traditional view of Markovnikov’s rule, the asymmetric alkene shoulod contain a hydrogen atom. What is more, the structure of alkene and the composition of reagent are limited, too. Therefore, this method has its limitations. However, when Markovnikov’s rule is seen essentially from the aspect of the influence of electronic effect, the orientation of electrophilic addition reaction of any asymmetric reagent and asymmetric alkene can be explained.
