Definition of Halogenation

Halogenation is a chemical process in which one or more molecules of halogen (F, Cl, Br, I) is/are added to a chemical compound or material. Not only organic compounds but inorganic compounds also undergo the process of halogenation. The pathways through which halogenation is done are dependent on both the structure of the molecule which is to be halogenated and on the specific halogen as well.


The pathways for halogenation include free-radical halogenation, electrophilic halogenation, ketone halogenation, etc. The halogens which are known to be more electrophilic tend to be good halogenating agents for example fluorine and chlorine. Iodine is the weakest halogenating agent among them.
