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 theoretically tennesside compound.
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]
Halide ligands may be abstracted by silver(I), often as the tetrafluoroborate or the hexafluorophosphate. In many transition metal compounds, the empty coordination site is stabilized by a coordinating solvent like tetrahydrofuran. Halide ligands may also be displaced by the alkali salt of an X-type ligand, such as a salen-type ligand. [10]
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 This category has the following 13 subcategories, out of 13 total.
A silver halide (or silver salt) is one of the chemical compounds that can form between the element silver (Ag) and one of the halogens.In particular, bromine (Br), chlorine (Cl), iodine (I) and fluorine (F) may each combine with silver to produce silver bromide (AgBr), silver chloride (AgCl), silver iodide (AgI), and four forms of silver fluoride, respectively.
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]
An acyl halide (also known as an acid halide) is a chemical compound derived from an oxoacid [1] by replacing a hydroxyl group (−OH) with a halide group (−X, where X is a halogen). [ 2 ] In organic chemistry , the term typically refers to acyl halides of carboxylic acids ( −C(=O)OH ), which contain a −C(=O)X functional group consisting ...
The acid cobalt tetracarbonyl hydride HCo(CO) 4 is in fact quite a strong acid, though its low solubility renders it not as strong as the true hydrogen halide. The behavior and chemical properties of the above pseudohalides are identical to that of the true halide ions.
