Problem: The compound below is treated with N-bromosuccinimide (NBS) in the presence of light.Draw both resonance structures for the radical produced by reaction of the compound with a bromine atom. Assume reaction occurs only at the weakest C-H bond.You do not have to consider stereochemistry.You do not have to explicitly draw H atoms.Separate resonance structures using the ? symbol from the dropdown menu.Include all valence radical electrons in your answer.

Using NBS will add a Br to the alkene via allylic radical bromination.

  • In the mechanism, a radical will be formed.
  • The radical can resonate due to the double bond present.
