WebMay 9, 2024 · The addition of bromine to water generates hypobromous acid (HOBr) and hydrobromic acid (HBr). Depending on the pH, HOBr can further convert to hypobromite (OBr – ). In 1938, Shilov and Gladtchikova 13 correctly measured a pK a value of 8.7 for the HOBr – OBr – conversion. Br 2 + H 2 O = HOBr + HBr HOBr + OH – = OBr – + H 2 O pK … WebAromatic compounds undergo bromination simultaneously with evolution of hydrogen bromide. Catalysts such as AlBr3 or FeBr3 are needed for the reaction to happen on aromatic rings. Chlorine-based catalysts (FeCl3, AlCl3) could be used, but yield would drop slightly as dihalogens (BrCl) could form.
