Detailed explanation-1: -We said earlier that the reaction of HCl and HBr (among others) with alkenes is “regioselective”. In this post we give several examples of these regioselective reactions and trace them back to the observations of a Russian chemist in the 1880’s, Vladimir Markovnikov.
Detailed explanation-2: -Hydrogen halides react with alkenes to give alkyl halides. This process is called electrophilic addition because the addition of an electrophilic proton initiates the reaction. Addition of hydrogen halides is regiospecific.
Detailed explanation-3: -When alkenes react with hydrogen gas in the presence of a variety of metal catalysts, a hydrogen molecule will be added to the double bond in a way that each carbon atom bonds with one hydrogen atom. Such an addition reaction is called hydrogenation.
