WebbWhen alcohols react with a hydrogen halide, a substitution occurs, producing an alkyl halide and water: Scope of Reaction The order of reactivity of alcohols is 3° > 2° > 1° methyl. The order of reactivity of the hydrogen halides is HI > HBr > HCl (HF is generally unreactive). The reaction is acid catalyzed.
