Question

Write the reaction mechanism of hydrogen bromide reaction​

Answer 1

Answer:

The reaction occurs when a proton adds to the triple bond to form an alkenyl carbocation, which the nucleophilic bromide ion subsequently captures. Of the two possible carbocations, the secondary is more stable than the primary because the secondary carbocation is more highly substituted.

Answer 2

Explanation:

Electrophilic addition reactions involving hydrogen bromide Alkenes react with hydrogen bromide in the cold. The double bond breaks and a hydrogen atom ends up attached to one of the carbons and a bromine atom to the other. In the case of ethene, bromoethane is formed.
