Which of the products will be major product in the reaction given below?

Explain.


CH3CH=CH2 + HI CH3CH2CH2I + CH3CHICH3


(A) (B)



This addition reaction is carried out by following Markovnikoff’s rule, where in a double bond, the hydrogen from the hydrogen halide is added to the carbon atom with the most hydrogen atoms attached to it, while the halogen atom is attached to the carbon atom with lesser hydrogens. The molecule that follows this rule will be the major product in the mixture. Hence, the molecule (B) will be the major product in the reaction.
