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.

What is the reverse of Markovnikov's rule?
The reverse of Markovnikov's rule is called anti-Markovnikov addition. In anti-Markovnikov addition, the electrophile adds to the carbon atom with fewer hydrogen atoms in the presence of certain catalysts or peroxides. This results in the formation of a less substituted alkene product compared to the traditional Markovnikov addition.
Which compound obeys Markovnikov rule on reaction with HCl?
This is an assymetric alkene.
What is markownkoves rule?
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.
When was Nikolai Markovnikov born?
Nikolai Markovnikov was born in 1869.
When did Nikolai Markovnikov die?
Nikolai Markovnikov died in 1942.
When did Vladimir Markovnikov die?
Vladimir Markovnikov died on 1904-02-11.
When was Vladimir Markovnikov born?
Vladimir Markovnikov was born on 1837-12-22.
What is the kharasch effect?
anti markovnikov addition
What is a basic explanation of Markovnikov's rule?
Markovnikov's rule states that in the addition of a protic acid to an alkene, the hydrogen atom will preferentially bond to the carbon atom with more hydrogen atoms attached, while the functional group will bond to the carbon atom with fewer hydrogen atoms. This is due to the formation of a more stable carbocation intermediate during the reaction.
What is markownikovs rule?
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.
What is Markonikoff's rule in Chemistry?
Markovnikov's rule states that when a hydrogen halide (such as HCl or HBr) adds to an alkene, the hydrogen atom attaches to the carbon atom with more hydrogen atoms already bonded to it, while the halogen atom attaches to the carbon atom with fewer hydrogen atoms bonded to it. This rule helps predict the regioselectivity of certain addition reactions to alkenes.
