Answer to Question #27996 in Organic Chemistry for Chandan

Question

what happens when 1 propene is treated with hbr

Answer 1

When one propene is treated with HBr, the reaction occurs at the Markovnikov rule, which states that the proton is attached to the most hydrogenated carbon atom.
Write the reaction:

CH₂=CH-CH₃ + HBr --> CH₃-CH(Br)-CH₃

In the presence of peroxides can be a reaction against the Markovnikov rule:

CH₂=CH-CH₃ + HBr => (ROOR) => CH₂(Br)-CH₂-CH₃
