Markovnikov

Hydrogen joins carbon

Markovnikov refers to a rule in organic chemistry predicting where hydrogen atoms attach during addition reactions to alkenes.

The Markovnikov rule states that hydrogen adds to the carbon already bearing more hydrogens: The reaction followed Markovnikov's rule, placing the hydroxyl group on the more substituted carbon.

Anti-Markovnikov describes the opposite outcome.

Named for Russian chemist Vladimir Markovnikov.
