Allyl Radical:An allyl radical is a reactive intermediate formed during allylic bromination, where the unpaired electron is delocalized over three carbon atoms, increasing its stability.
Resonance Stabilization:Resonance stabilization refers to the increased stability of the allyl radical due to the delocalization of the unpaired electron, which is a key factor in the mechanism of allylic bromination.
Allylic Substitution: Allylic substitution is a type of nucleophilic substitution reaction that occurs at the carbon atom adjacent to a carbon-carbon double bond, often involving the displacement of a halogen atom.
