explain markoniv and anti markoniv mechanism of unnnsymetrical alkene?
When an unsymmetrical alkene reacts with a hydrogen halide to give an alkyl halide, the hydrogen adds to the carbon of the alkene that has the greater number of hydrogen substituents, and the halogen to the carbon of the alkene with the fewer number of hydrogen substituents.
Anti Markovnikov’s rule:
In an addition reaction of a generic electrophile HX to an alkene or alkyne, the hydrogen atom of HX becomes bonded to the carbon atom that had the least number of hydrogen atoms in the starting alkene or alkyne. The ‘anti’ in 'anti-Markovnikov’s refers to the fact the reaction does not follow Markovnikov’s rule, instead of being a reference to anti addition stereochemistry.
