Nomenclature of Halogen Derivative Compounds
On this page we will discuss the nomenclature of halogen derivative compounds. We are assuming you have read our previous tutorials or you know the basic rules of nomenclature.
Halogen family
Fluorine, Chlorine, Bromine, Iodines are the members of halogen family.
Prefix Halo
Halo groups are always treated as substituents. Halo (fluoro, chloro, bromo, iodo) is prefixed to word root to indicate the presence of a halogen.
