WebConversion of Alcohols into Alkyl Halides. When alcohols react with a hydrogen halide, a substitution takes place producing an alkyl halide and water: 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. WebSep 9, 2015 · If pure hydrochloric acid is added to a sample of pure copper, there is essentially no reaction; the solution should not turn blue. At a guess, you're seeing the copper turn pink because it has a significant oxide layer that is reacting with the acid, forming copper (II) chloride and leaving bare the pinkish metal. The solution could be … WebReactivity Profile. HYDROCHLORIC ACID is an aqueous solution of hydrogen chloride, an acidic gas.
