Concept introduction:
In an addition of a Bronsted acid across a double bond, the proton can bond to one of the two possible carbon atoms. The major product of an electrophilic addition of a Bronsted acid to an alkene is the one that proceeds through the more stable carbocation intermediate. If alkene is symmetrical, then it results in only one product. If an alkene is unsymmetrical, then two constitutional isomers can be produced. The major product is the one in which a more stable carbocation intermediate is produced. Tertiary carbocation is the most stable, followed by secondary and then primary. Methyl carbocations are least stable.
