Markovnikov's rule (Markovnikov addition): In an addition reaction of a protic acid HX (hydrogen chloride, hydrogen bromide

, or hydrogen iodide) to an alkene or alkyne, the hydrogen atom of HX becomes bonded to the carbon atom that had the greatest number of hydrogen atoms in the starting alkene or alkyne.

What reactions use Markovnikov's rule?

Markovnikov's rule is an empirical rule used to predict regioselectivity of electrophilic addition reactions of alkenes and alkynes.

How do you know if a reaction is Markovnikov or anti Markovnikov?

The main difference between Markovnikov and Anti Markovnikov rule is that Markovnikov rule indicates that hydrogen atoms in an addition reaction are attached to the carbon atom with more hydrogen substituents whereas Anti Markovnikov rule indicates that hydrogen atoms are attached to the carbon atom with the least ...
