You organic halides are compounds which have at least one halogen atom attached to a hydrocarbon-derived radical.
Like virtually all organic functional groups, halides also have usual naming rules. However, these rules only apply to monohalides, that is, to those halides that have only one halogen attached to the carbon in the molecule.
As seen in the text "Organic Halides Nomenclature”, in the official nomenclature designated by the IUPAC (International Union of Pure and Applied Chemistry), halogens are considered as radicals. In the usual nomenclature, however, the opposite occurs: everything that is attached to halogen is considered a substituent.
Therefore, the usual naming scheme for organic halides becomes the following:
