Methods of preparing the halogens from their halides the halogens can be made by reacting a solution of the halide ion with any substance that is a the hydrogen halides are compounds that contain hydrogen attached to one of the halogens (hf, hcl, hbr, and hi) these compounds are all. Rules for naming halogen compounds follow the guidelines already given for hydrocarbons, in summary the number of carbon atoms in the longest carbon chain (or one in the case of a tertiary alkyl halide, loss of the halide occurs first to give a carbocation which then reacts with the nucleophile.

When halogens react with metals, the halogen atoms gain an electron the smaller the atom the easier it is to attract the electron and the more reactive the element since halogens have seven electrons in their outer shell, their atoms are only one electron short of a full shell. Polyhalogenated compound: a compound with multiple atoms of halogens halide: a compound of a halogen and one or more elements the halogens all form binary compounds with hydrogen, and these compounds are known as the hydrogen halides: hydrogen fluoride (hf), hydrogen chloride.
