What type of reaction occurs when C3H6 reacts with Br2 to form C3H6Br2?

Explanation:
When an alkene reacts with bromine, it undergoes an addition reaction across the carbon–carbon double bond. The Br2 molecule is pulled in by the electron-rich double bond, the bond breaks, and two bromine atoms become attached to the two carbons that were part of the double bond. For propene, C3H6 + Br2 adds to give C3H6Br2, a dibrominated product with no remaining double bond. This is different from elimination (which would restore or form a double bond) or substitution (which would replace a hydrogen with bromine without removing the double bond) and certainly not combustion (which requires oxygen and produces CO2 and H2O).
