(ii) Draw the structure of, and give the name of, the addition product formed when buta-1,3-diene reacts with an excess of bromine. Name the type of mechanism involved. Structure of product WebJun 21, 2024 · The most likely product is 1,2-dibromo-4-methylpentane. > The reaction of an alkene with bromine gives a vicinal dibromide (a 1,2-dibromide). Thus, the reaction of bromine with 4-methylpent-1-ene gives 1,2-dibromo-4-methylpentane. The mechanism The electrons in the π bond of the approaching alkene induce a dipole in the highly …
