Markovnikov’s rule is an empirical rule used to predict regioselectivity of electrophilic addition reactions of alkenes and alkynes. It states that, in hydrohalogenation of an unsymmetrical alkene, the hydrogen atom in the hydrogen halide forms a bond with the doubly bonded carbon atom in the alkene, bearing the greater number of hydrogen atoms.
Markonikov's rule is related to addition reactions so its reverse should be related to elimination reaction so it may be Saytzef's rule which states that during elimination reaction hydrogen is removed from that carbon atom which has the lesser no of hydrogen atoms.
This is an assymetric alkene.
Markovnikov's rule states that functional groups tend to be added to the more substited carbon. For alcohol groups, Oxymercuration-demercuration of a double bond in and alkene results in the Markovnikov product with the hydroxyl group on the more substituted carbon. Hydroboration-Oxidation of a double bond in an alkene results in the Anti-Markovnikov product with the hydroxyl group on the less substituted carbon.
Nikolai Markovnikov was born in 1869.
Nikolai Markovnikov died in 1942.
Vladimir Markovnikov died on 1904-02-11.
Vladimir Markovnikov was born on 1837-12-22.
In Markovnikov reactions, the hydrogen atom adds to the carbon atom with more hydrogen atoms already attached, while in anti-Markovnikov reactions, the hydrogen atom adds to the carbon atom with fewer hydrogen atoms attached.
anti markovnikov addition
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.
Markovnikov's rule states that in the addition of a hydrogen halide (such as HCl or HBr) to an alkene, the hydrogen atom will add to the carbon atom with more hydrogen substituents, while the halogen atom will add to the carbon atom with fewer hydrogen substituents.
Markonikoff's rule states that when an ionic reagent is added to an unsaturated compound, the negative addendum goes to that carbon atom which contains the lesser number of hydrogen atoms or no hydrogen at all.
