The structure of a carbocation intermediate formed in the addition reaction of HBr to two different alkenes is given. The structures of both alkenes are to be given. Concept introduction: In electrophilic addition reactions the first step involves the attack of the π electrons of the double bond on the positively polarized hydrogen atom of the hydrogen halide to give a carbocation as the product with the elimination of a halide ion. In the second step the carbocation reacts with the halide ion to give the product. To draw: The structures of two alkenes that yield the carbocation intermediate given in an addition reaction with HBr.
