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 which will yield the alkyl halide given as product in an addition reaction with HBr.
Answer to Problem 14VC
The structures of two alkenes which will yield the alkyl halide given as product in an addition reaction with HBr are given below.
Explanation of Solution
Both 1-pentene and 2-pentene have double bonds in a position to yield the alkyl bromide when treated with HBr.
The structures of two alkenes which will yield the alkyl halide given as product in an addition reaction with HBr are given below.
