halogeniide

Halogeniide is a term that can refer to several different chemical concepts, primarily related to the halogens. One common meaning is a compound containing a halogen atom bonded to another element or group, often in a negatively charged ion. For example, chloride (Cl-) or bromide (Br-) ions are considered halide ions, and compounds containing them, like sodium chloride (NaCl) or potassium bromide (KBr), are binary ionic compounds where the halogen acts as the anion. In organic chemistry, the term can also describe organic compounds where a halogen atom is covalently bonded to a carbon atom, such as chloromethane (CH3Cl) or bromoethane (CH3CH2Br). These are often referred to as organohalogen compounds or alkyl halides.

Another context for "halogeniide" might arise in discussions of interhalogen compounds, which are molecules containing two or more different halogen atoms, such as chlorine trifluoride (ClF3) or bromine pentafluoride (BrF5). These compounds exhibit unique reactivity and bonding characteristics. The term "halogeniide" itself is less common in formal chemical nomenclature and might be a more general or colloquial way to describe a species where a halogen plays a key anionic or substituent role. The specific meaning depends heavily on the context in which it is used.
