Radii in picometers of common halogen atoms (gray/black) and the corresponding halide anions (blue) In chemistry, a halide (rarely halogenide [1]) is a binary chemical compound, of which one part is a halogen atom and the other part is an element or radical that is less electronegative (or more electropositive) than the halogen, to make a fluoride, chloride, bromide, iodide, astatide, or ...
Examples of non-symmetrical pseudohalogen compounds (pseudohalogen halides Ps−X, where Ps is a pseudohalogen and X is a halogen, or interpseudohalogens Ps 1 −Ps 2, where Ps 1 and Ps 2 are two different pseudohalogens), analogous to the binary interhalogen compounds, are cyanogen halides like cyanogen chloride (Cl−CN), cyanogen bromide (Br ...
Halides are compounds containing halogens. The halogens may either be bonded to another element through covalent bonding or (as in many metal halides) present in the form of the halide ion . Subcategories
Halide minerals are those minerals with a dominant halide anion (F −, Cl −, Br − and I −). Complex halide minerals may also have polyatomic anions. [1] Halite Fluorite structure. Examples include the following: [2] [3] Atacamite Cu 2 Cl(OH) 3; Avogadrite (K,Cs)BF; Bararite (β) (NH 4) 2 SiF 6 [4] Bischofite MgCl 2 ·6H 2 O; Brüggenite ...
Alkali metal halides, or alkali halides, are the family of inorganic compounds with the chemical formula MX, where M is an alkali metal and X is a halogen. These compounds are the often commercially significant sources of these metals and halides. The best known of these compounds is sodium chloride, table salt. [1]
In chemistry, hydrogen halides (hydrohalic acids when in the aqueous phase) are diatomic, inorganic compounds that function as Arrhenius acids. The formula is HX where X is one of the halogens: fluorine, chlorine, bromine, iodine, astatine, or tennessine. [1] All known hydrogen halides are gases at standard temperature and pressure. [2]
Heating the higher halides may produce the lower halides; this occurs by thermal decomposition or by disproportionation. For example, gold(III) chloride to gold(I) chloride: [1] AuCl 3 → AuCl + Cl 2 at 160°C. Metal halides are also prepared by the neutralization of a metal oxide, hydroxide, or carbonate with the appropriate halogen acid.
In chemistry, a sulfonyl halide consists of a sulfonyl (>S(=O) 2) group singly bonded to a halogen atom. They have the general formula RSO 2 X, where X is a halogen. The stability of sulfonyl halides decreases in the order fluorides > chlorides > bromides > iodides, all four types being well known. The sulfonyl chlorides and fluorides are of ...
