In chemistry, an oxocarbon anion is a negative ion consisting solely of carbon and oxygen atoms, and therefore having the general formula C x O n− y for some integers x, y, and n. The most common oxocarbon anions are carbonate, CO 2− 3, and oxalate, C 2 O 2− 4. There are however a large number of stable anions in this class, including ...
In chemistry, an oxocarbon or oxide of carbon is a chemical compound consisting only of carbon and oxygen. [ 1 ] [ 2 ] The simplest and most common oxocarbons are carbon monoxide (CO) and carbon dioxide ( CO 2 ).
In chemistry, peroxycarbonate (sometimes peroxocarbonate, IUPAC name: oxocarbonate or oxidocarbonate) or percarbonate is a divalent anion with formula CO 2− 4. It is an oxocarbon anion that consists solely of carbon and oxygen. It is the anion of peroxycarbonic acid [1] [2] also called hydroperoxyformic acid, [3] HO−O−CO−OH.
In organic chemistry a carbonate can also refer to a functional group within a larger molecule that contains a carbon atom bound to three oxygen atoms, one of which is double bonded. These compounds are also known as organocarbonates or carbonate esters, and have the general formula R−O−C(=O)−O−R′ , or RR′CO 3 .
In chemistry, peroxydicarbonate (sometimes peroxodicarbonate) is a divalent anion with the chemical formula C 2 O 2− 6. It is one of the oxocarbon anions, which consist solely of carbon and oxygen. Its molecular structure can be viewed as two carbonate anions joined so as to form a peroxide bridge –O–O–.
There are several oxocarbon anions, negative ions that consist solely of oxygen and carbon. The most common are the carbonate (CO 3 2−) and oxalate (C 2 O 4 2−). The corresponding acids are the highly unstable carbonic acid (H 2 CO 3) and the quite stable oxalic acid (H 2 C 2 O 4), respectively.
Dioxosuccinic acid or dioxobutanedioic acid is an organic compound with formula C 4 H 2 O 6 or HO−(C=O) 4 −OH. Removal of two protons from the molecule would yield the dioxosuccinate anion, C 4 O 2− 6 or − O−(C=O) 4 −O −. This is one of the oxocarbon anions, which consist solely of carbon and oxygen.
The remainder of this article will focus on alkyl oxocarbenium ions, however, where the atom added to the oxygen is a carbon. One way that this sort of ion will form is the elimination of a leaving group. In carbohydrate chemistry, this leaving group is often an ether or ester. An alternative to elimination is direct deprotonation of the ...
