That is,an addition reaction might invole the addition of HBr or H2O to an alkene to form an alkyl halide or alcohol, whereas an elimination reactionthe might involve the loss of HBr or H2O from an alkyl halide or alcohol to form an alkene.
Ntawd ces yog qhov sib ntxiv cov tshuaj tiv thaiv tej invole qhov sib ntxiv ntawm HBr los yog H2O rau ib alkene tsim tau ib lub alkyl halide los yog quav dej caw, whereas ib tus reactionthe ntaus tej zaum cia tsis tau HBr los yog H2O ib alkyl halide los haus dej caw yuav tsim tau ib lub alkene.
