H 2 + Br 2 Possible mechanism of this … Hydrobromic acid is mainly used for the production of inorganic bromides, especially the bromides of zinc, calcium, and sodium. It is a useful reagent for generating organobromine compounds. Certain ethers are cleaved with HBr. It also catalyzes alkylation reactions and the extraction of certain ores. Industrially significant organic compounds prepared from hydrobromic acid include allyl bromide, tetrabromobis(phenol), and bromoacetic acid. HBr almost uniquely participates in …

Hydrogen bromide and hydrobromic acid are important reagents in the production of organobromine compounds. In a free-radical reaction, HBr adds to alkenes: RCH=CH2 + HBr → R−CHBr−CH3 The resulting alkyl bromides are useful alkylating agents, e.g., as precursors to fatty amine derivatives. Related free radical additions to allyl chloride and styrene give 1-bromo-3-chloropropa…
