What is a basic explanation of Markovnikov's rule?

Answer 1

This the addition of hydrogen or proton of an acid to the carbon double bond that has already has the most hydrogen i.e "the rich get the richer"

In a reaction involving carbon - carbon double bond, in a electrophilic additon to an alkene, the electrophilic adds in such a way to form the most stable intermediate. HCL, HBr and HI add to alkene to form markovnikov's products.

Answer 2

Markovnikov's rule states that in the addition of a protic acid to an alkene, the hydrogen atom will preferentially bond to the carbon atom with more hydrogen atoms attached, while the functional group will bond to the carbon atom with fewer hydrogen atoms. This is due to the formation of a more stable carbocation intermediate during the reaction.
