APA TEGESÉ ONIUM SALT ING BASA INGGRIS?

Senyawa onium

Onium compound

Ing kimia, senyawa onium, utawa onium ion, minangka kation sacara resmi ditampa kanthi protonasi hidrida induk mononuklear saka pnictogen, chalcogen, utawa halogen. Asam sing paling tuwa lan sing jenenge kanggo kelas yaiku amonium, NH + 4, turunan protonated amonia, NH 3. Jeneng onium uga digunakake kanggo kation sing bakal nyebabake substitusi atom hidrogen ing ion kasebut kelompok liyane, kayata radikal organik, utawa halogens; kayata tetraphenylphosphonium, 4P +. Klompok substituen bisa uga di-trivalen, ngasilake ion kayata iminium lan nitrilium. Ion ionium duweni daya saka +1. A molekul sing nganggo subkumpulan rong utawa luwih onium diarani minangka ion onium, telung onium ion, lan sateruse. Senyawa saka kation onium lan sawetara ion negatif liya uga dikenal minangka uyah onium. Senyawa onium sing padha karo senyawa sing padha. Basis Lewis mbentuk ion onium nalika atom pusat ngalami siji ikatan lan dadi kation positif. Asam Lewis mbentuk ion-ion nalika atom pusat ngalami siji ikatan lan dadi 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.
