In view of the increasing demand for sustainable synthetic chemistry, oxidative bromination can play an important role to avoid the use of hazardous molecular bromine (Br 2 ).
WebbThe oxidation state of an atom is a measure of the degree of oxidation of an atom. It is defined as being the charge that an atom would have if all bonds were ionic. Uncombined elements have an oxidation state of 0. The sum of the oxidation states within a compound or ion must equal the overall charge. Isotopes
