Addition of HBr to propene in the presence of peroxide follows which rule?

Question

Accepted Answer

In the presence of organic peroxides (like benzoyl peroxide), the addition of unsymmetrical reagents like HBr to unsymmetrical alkenes like propene takes place via a free-radical mechanism, which yields anti-Markovnikov's product (1-bromopropane). This is also known as the peroxide effect or Kharasch effect.
