  Vladimir Vasilevich Markovnikov - Wikipedia, the free encyclopedia
Vladimir Vasilevich Markovnikov (December 22, 1838 in Nizhny Novgorod - February 1904) was a Russian chemist.
Markovnikov is best known for the Markovnikov's rule which he developed in 1869.
Markovnikov also contributed to organic chemistry by finding carbon rings with more than six carbon atoms, a ring with four carbon atoms in 1879, and a ring with seven in 1889.

 Vladimir Vasilevich Markovnikov
Vladimir Vasilevich Markovnikov (also spelled Markownikoff) was a Russian chemist.
Markovnikov is best known for predicting the regiochemistry of addition reactions of hydrogen halides[?], sulfuric acid, water, ammonia, and other (small) molecules to unsymmetrical alkenes.
Markovnikov also showed that butyric acid and isobutyric acid[?] are isomers (they do have the same chemical formula but different structures).

 Markovnikov's rule - Wikipedia, the free encyclopedia   (Site not responding. Last check: 2007-10-07)
It was formulated by the Russian chemist Vladimir Vasilevich Markovnikov.
Therefore when a molecule of the form HX (where X is more electronegative than H) is added in an addition reaction to a carbon-carbon double bond, the H is added to the less substituted carbon atom, while the X is added to the more substituted.
The rule may be summed up by quoting that the rich get richer and the poor get poorer, in that a carbon rich in substituents will get more substituents and the carbon with more hydrogens attached will get the hydrogen in case of many different organic addition reactions.

 Vladimir Markovnikov - Wikipedia
Vladimir Vasilevich Markovnikov (Nizhny Novgorod 22 dicembre 1838, 11 febbraio 1904) fu un chimico russo noto soprattutto per la regola che ne porta il nome.
Iniziò i suoi studi all'Università di Kazan come studente di legge ma ben presto rimase affascinato dalle lezioni di chimica di Alexandr Butlerov di cui divenne assistente subito dopo la laurea nel 1860.
È interessante notare che il forte spirito nazionalista di Markovnikov lo spinse a pubblicare i propri lavori quasi esclusivamente in russo.

Zaitsevs rule states that, in elimination reactions, the major reaction product is the alkene with the more highly substituted double bond.
A chemical reaction is a process involving one, two or more substances (called reactants), characterized by a chemical change and yielding one or more product(s) which are different from the reactants.
An addition reaction, in chemistry, is a reaction where two molecules combine to form a larger one.
