Halogen alkene reaction
WebFeb 27, 2024 · The alkene hydrohalogenation reaction is an electrophilic addition reaction which converts alkenes into alkyl halides. The alkene reacts with a hydrogen halide (HX, where X is Cl, Br, or I), breaking the alkene π bond, adding a hydrogen to one alkene carbon, and adding a halogen atom (Cl, Br, or I) to the other. WebAddition reactions of alkenes. The functional group, C=C, allows alkenes to undergo addition reactions. For example, ethene reacts with bromine to form 1,2-dibromoethane:
