Process of Drawing Hydrohalogenation with a Carbocation Rearrangement ?
Hydrohalogenation is an electrophilic addition reaction in which an electrophilic agent adds to a carbon-carbon double bond.
In hydrohalogenation, the addition of HX takes place to a carbon-carbon double bond.
The H+ ion gets added first and then X- gets added in the last step.
The reaction involves the addition of a proton to the double bond first, giving a cyclic intermediate which then breaks to give a carbocation.
The addition of a proton to the double bond follows Markovnikoff's rule according to which it adds to a less substituted carbon atom, giving a more stable carbocation.
The X- then attacks the carbocation, giving the final product.
