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

Explain


CH3CHICH3, is the major product of the reaction. The mechanism of the reaction will be as follows

HIH+ + I-
CH3CH=CH2CH3Ha  C+H CH3 2°Carbocation (more stable)
                                      CH3CH2C+H2 1° Carbocation (less stable)
CH3C+HCH3I-CH3CHCH3
                                                        |
                                                        I
