WebIn general, we can predict the major product of the hydrohalogenation of an unsymmetrical alkene using Markovnikov’s rule. Markovnikov’s rule states that the acidic hydrogen atom will add to the carbon of the double bond that has the greatest number of hydrogen substituents. WebWith HBr, propene readily reacts and give 2-bromopropane as the major product and 1-bromopropane as the minor product. CH 3 CH=CH 2 + HBr → CH 3 CHBrCH 3. CH 3 CHBrCH 3 (2-bromopropane) is given as the major product. HBr molecule is added across the double bond of propene. Marconikov rule is used to find the locations (to which …

WebReaction Overview: The hydrohalogenation of alkenes involves breaking a carbon to carbon double bond, followed by the electrophilic addition of a hydrogen atom and halogen.
