Markovnikov\u2019s rule predicts the regiochemistry of the reaction when a protic acid (usually denoted by HX) is added to an unsymmetrically substituted alkene. It predicts that the halide part of the protic acid preferentially attaches itself to highly substituted carbon atoms whereas the hydrogen component of the protic acid preferentially attaches itself to the least substituted carbon atom (the carbon atom holding the most carbon-hydrogen bonds).<\/p>\n\n\n\n
Free radical addition reactions do not obey Markovnikov\u2019s rule since the regioselectivity of the mechanisms of these reactions is not predicted by Markovnikov\u2019s rule. These reactions are generally referred to as Anti-Markovnikov addition reactions.<\/p>\n\n\n\n
Markovnikov\u2019s rule states that when an asymmetrical reagent is added to an asymmetrical alkene, then the negative half of the reagent will attach to the carbon atom containing fewer hydrogen atoms.<\/p>\n\n\n\n
The addition of hydrogen halide to an unsymmetrical alkene follows markovnikov\u2019s rule in the absence of hydrogen peroxide.<\/p>\n\n\n\n
Markovnikov\u2019s rule works on the basis of the formation of the most stable carbocation during the addition reaction. However, it does fail in the presence of peroxide and symmetrical alkenes.<\/p>\n\n\n\n
The modification in regioselectivity of the addition of HBr to an alkene or alkyne in the presence of peroxide is known as the peroxide effect. Under the presence of a peroxide, the negative half of the reagent will attach to the carbon atom containing more hydrogen atoms.<\/p>\n\n\n\n
