Discuss Markovnikov's rule and Kharash effect.

Addition of HX on alkene proceed through formation of carbocation . This reaction is follows Markovnikov's rule. According to markovnikov's rule addition of electrophile occurs on that carbon of alkene which have more number of -H atom Ph-CH = CH_2 underset(HX)to underset("(major)")(Ph-overset(x)overset(|)CH-CH_3) + underset("(minor)")(Ph-CH_2-CH_2-X) Which of the following alkenes will give markovnikov's reaction ?

Markovnikov addition takes place with unsymmetrical alkenes. The positive part of the reagent gets connected to the double bonded carbon with more number of hydrogens. In presence of peroxide and in special cases addition takes place against Markovnikov rule. In which of the following compound addition takes place against Markovnikov rule

Among the following which is less than ethene but gives Markovnikov's product in the addition of HBr

Discuss on : (ii) Sulphates.
