Question

Addition of bromine on propene yields

• A. 1,2-dibromopropane
• B. 2,2-dibromopropane
• C. 1,1-dibromopropane
• D. 1,3-dibromopropane

Answer 1

The correct option is A 1,2-dibromopropane

Halogens like Br, Cl and I add up to alkenes to form vicinal dihalides. Addition of halogens to alkenes​ is an example of electrophilic​ addition reaction. It involves two steps. In step-1 halonium ion is formed. In step-2 attack of $X^{-}$ on halonium ion occurs. Thus addition of bromine on propene yields 1,2-dibromopropane


Hence, the correct answer will be option (a).
