Which of the products will be major product in the reaction given below? Explain.
`CH_(3)CH = CH_(2)+HI rarr CH_(3)CH_(2)CH_(2)I(A)+CH_(3)CHICH_(3)(B)`

Explanation

This addition reaction proceeds via the formation of carboncation intermidiate. Since `2^(@)` carbocation `CH_(3)overset(o+)(C)H-CH_(3)` is more stable than `1^(@)` carbocation `CH_(3)CH_(2)CH_(2)`, therefore, the major product is `CH_(3)-CHI-CH_(3)`.
