APAKAH MAKSUD ONIUM SALT dalam CORSICA?

Sebatian onium

Onium compound

Dalam kimia, sebatian onium, atau ion onium, adalah kation secara rasmi diperolehi oleh protonasi hidrida induk mononuklear daripada pnictogen, chalcogen, atau halogen. Ion tertua yang tertua dan nama untuk kelas ialah ammonium, NH + 4, derivatif protonated ammonia, NH 3. Nama onium juga digunakan untuk kation yang akan terhasil daripada penggantian atom hidrogen dalam ion tersebut oleh kumpulan lain, seperti radikal organik, atau halogens; seperti tetraphenylphosphonium, 4P +. Kumpulan substituen boleh di- atau trivalen, menghasilkan ion seperti iminium dan nitrilium. Ion onium mempunyai caj +1. Satu molekul dengan dua atau lebih subkumpulan ion onium dikatakan ion ganda onium, triple onium ion, dan sebagainya. Sebatian kation onium dan beberapa ion negatif lain dikenali sebagai garam onium. Sebatian onium adalah sama dengan komplek makan. Basikal Lewis membentuk ion onium apabila atom pusat mendapat satu lagi ikatan dan menjadi kation positif. Asid Lewis membentuk ion-ion apabila atom pusat mendapat satu lagi ikatan dan menjadi anion negatif.

In chemistry, an onium compound, or onium ion, is a cation formally obtained by the protonation of mononuclear parent hydride of a pnictogen, chalcogen, or halogen. The oldest-known onium ion, and the namesake for the class, is ammonium, NH+ 4, the protonated derivative of ammonia, NH 3. The name onium is also used for cations that would result from the substitution of hydrogen atoms in those ions by other groups, such as organic radicals, or halogens; such as tetraphenylphosphonium, 4P+. The substituent groups may be di- or trivalent, yielding ions such as iminium and nitrilium. Onium ions have a charge of +1. A molecule with two or more onium ion subgroups is said to be a double onium ion, triple onium ion, and so on. Compounds of an onium cation and some other negative ion are known as onium salts. Onium compounds are inversely analogous to ate complexes. Lewis bases form onium ions when the central atom gains one more bond and becomes a positive cation. Lewis acids form -ate ions when the central atom gains one more bond and becomes a negative anion.
