In the presence of light, the addition of Br 2 to alkenes can occur by a free-radical

Question:

In the presence of light, the addition of Br2 to alkenes can occur by a free-radical mechanism rather than a bromonium-ion mechanism. Write a free-radical chain mechanism that shows the propagation steps for the following addition:Br + HC=CH light. BrCH CHBr


Assume that the initiation step for the reaction is the light-promoted homolysis of Br2:Br-Br light 2 Br.
