Russian scientist VV Markovnikov established that the reaction mechanism depends on the state of the carbon atoms in the double bond. The hypothesis put forward by the chemist was confirmed after discoveries in the field of the structure of the atom. Markovnikov's rule laid the foundation for the creation of a scientific theory that has practical application. It allows you to more rationally organize the production of polymers, lubricating oils, alcohols. Last modified: 2025-01-23 12:01
