Halogenation is a chemical reaction involving the addition of one or more halogens to a substance or material. The halogenation pathway and stoichiometry depends on the structural features and functional groups of the organic substrate, as well as on the specific halogen. Inorganic compounds, such as metals, are also halogenated. There are many mechanisms for halogenation of organic compounds, including free radical halogenation, ketone halogenation, electrophilic halogenation, and halogenic alternate reactions. The configuration of the substrate is a consideration that defines the pathway. The halogenation system is affected by the halogen. Fluorine and chlorine are more electrophilic and more powerful halogenating chemicals. Bromine is a slower halogenating agent than both fluorine and chlorine, whereas iodine is the least reactive of both. cases, the dissociation limit) and, consequently, a slower response rate.
