Vladimir vasilyevich markovnikov biography of william hamilton

Markovnikov was a Russian chemist who lived from to He studied at Kazan University and later went back to teach there. During his lifetime he was able to study chemistry and work in a laboratory know as "the cradle of Russian organic chemistry." His major accomplishment was made in in discovering the Markovnikov rule.

Biography of william shakespeare Vladimir Markovnikov was born on December 22, , in Chernorechye near Nizhny Novgorod, Russian Empire (now Dzerzhinsk, Nizhny Novgorod Oblast, Russian Federation) where at that time lodged the Belevsky Jaeger Regiment in which his father, Lieutenant Vasily Markovnikov, served.

This is very useful in predicting products in addition reactions. Markovnikov contributed to the structure of cyclic molecules.  He also discovered  that isobutyric and butyric acids are isomers. He is also discovered the four carbon ring and the seven carbon ring. Before this it was believed that there was only a six carbon ring.

He did most of research with organic chemistry. As you can see he made a lot of discoveries in his chemistry research.

Vladimir Vasilevich Markovnikov was born on December 22, , in Nizhny Novgorod, Russia.

Vladimir vasilyevich markovnikov biography of william shakespeare Vladimir Vasilyevich Markovnikov was a Russian organic chemist who contributed to structural theory and to the understanding of the ionic addition (Markovnikov addition) of hydrogen halides to the carbon-carbon double bond of alkenes.

He studied under Butlerov in Kazan and St. Petersburg. He had contributed to the field of organic chemistry by his discovery of the four-carbon ring in , and the seven-carbon ring in He was best unknown for "predicting the regiochemistry of addition reactions of hydrogen halides, sulfuric acid, water, ammonia, etc. to unsymmetrical alkenes. This is known as the Markovnikov Rule, which he developed in " Another important finding was that butyric and isobutyric acids are isomers of each other because they differ only in their structure, while sharing the exact same chemical formula.

Vladimir vasilyevich markovnikov biography of william Vladimir Vasilyevich Markovnikov, also Markownikoff [1] (Russian: Влади́мир Васи́льевич Марко́вников; 25 December [O.S. 13 December] – 11 February ) was a Russian chemist, [2] best known for having developed the Markovnikov's rule, that describes addition reactions of hydrogen halides and alkenes.

He passed away in February , Moscow, Russia.

Markovnikov worked with reactions of alkenes, and came up with a rule that states "When an unsymmetrically substituted alkene reacts with a hydrogen halide, the hydrogen adds to the carbon that has the greater number of hydrogens, and the halogen adds to the carbon having fewer hydrogens." This rule is very important when studying the mechanisms of reactions of alkenes.

In Alexander Erminingeldovich Arbuzov founded and headed the chemical institute of Kazan Branch of the USSR Academy of Sciences.  The institute received universal acknowledgement owing to the works of a group of chemistry researchers in which Vladimir Markovnikov was a part of.  Markovnikov’s rule states that  “ when an unsymmetrical alkene reacts with a hydrogen halide to give an alkyl halide, the hydrogen adds to the carbon that has the greater number of hydrogen substituents, and the halogen to the carbon have the fewer number of hydrogen substituents.  Markovnikov’s rule also included regiochemistry, which are the specific carbons of the alkene to which the H and the X attach.

Vladimir Markovnikov attended Russia’s Kazan University and had Alexander Butlerov as his chemistry teacher.  Markovnikov became Butlerov’s teacher assistant in   In , while working on his doctoral thesis, he developed the theory of chemical structure experimentally and theoretically.  A year later, he developed Markovnikov’s Rule, which states that when an unsymmetrically substituted alkene reacts with a hydrogen-halide, the hydrogen goes to the carbon with the most hydrogens and the halogen goes to the carbon with the least hydrogens.

Markovnikov also studied the composition of petroleum hydrocarbons to see if it has any practical use.  He became a chemistry professor at Moscow University from to

Vladimir Markovnikov was born on December 22, in Nizhny Novgorod, Russia.  He graduated in after studying with Butlerov in Kazan and in St.

Petersburg.  Following two years in Germany, he returned to Russia where he replaced Butlerov at the Kazan University.  Markovnikov died in February of in Moscow, Russia.

Markovnikov’s major contribution to the field of chemistry was in predicting the regiochemistry of the addition of a hydrogen halide to alkenes.  He theorized that when an alkene reacts with a hydrogen halide, the hydrogen from the hydrogen halide will add on to the carbon of the alkene that has the greatest number of hydrogens.  Furthermore, the halogen from the hydrogen halide will add on to the carbon of the alkene with the lower number of hydrogens.

            In addition, Markovnikov discovered that in cyclic molecules, four and seven carbon atom rings are possible structures along with six atom rings.  He also found butyric and isobutyric acids to be isomers because they possess the same chemical formula but have different structures.
