3. Completely explain the following observation: Br Br2 Br₂ Br Br + HBr A. Both reactions involve two bromine atoms adding across a double bond B. Both reactions involve a neutral intermediate with a single bromine atom C. After addition to benzene, elimination is favourable to regain aromaticity D. After addition to cyclohexene, the addition of a second bromine atom is favourable
