WebThe reaction is acid catalyzed. Alcohols react with the strongly acidic hydrogen halides HCl, HBr, and HI, but they do not react with nonacidic NaCl, NaBr, or NaI. Primary and secondary alcohols can be converted to alkyl chlorides and bromides by allowing them to react with a mixture of a sodium halide and sulfuric acid: WebHBr reacts with an alkene to form an alkyl bromides complex. It reacts with alcohol to form an alkyl bromide. It reacts with an alkyne to form a bromoalkene. It reacts with epoxide to form bromohydrin. It reacts with an alkyl halide to yield corresponding substitution production. It reacts with VCl 4 via a redox reaction to form the VBr 3 complex.
