Formally, a carbanion is the conjugate base of a carbon acid: R 3 CH + B − → R 3 C − + HB. where B stands for the base. The carbanions formed from deprotonation of alkanes (at an sp 3 carbon), alkenes (at an sp 2 carbon), arenes (at an sp 2 carbon), and alkynes (at an sp carbon) are known as alkyl, alkenyl , aryl, and alkynyl anions ...
Heterocycles with carbon in the rings may have limited non-carbon atoms in their rings (e.g., in lactones and lactams whose rings are rich in carbon but have limited number of non-carbon atoms), or be rich in non-carbon atoms and displaying significant symmetry (e.g., in the case of chelating macrocycles).
In chemistry, the oxidation state, or oxidation number, is the hypothetical charge of an atom if all of its bonds to other atoms were fully ionic.It describes the degree of oxidation (loss of electrons) of an atom in a chemical compound.
Four cycloalkanes, all of which exhibit simple rings. In chemistry, a ring is an ambiguous term referring either to a simple cycle of atoms and bonds in a molecule or to a connected set of atoms and bonds in which every atom and bond is a member of a cycle (also called a ring system).
There are many oxides of carbon , of which the most common are carbon dioxide (CO 2) and carbon monoxide (CO). Other less known oxides include carbon suboxide (C 3 O 2) and mellitic anhydride (C 12 O 9). [5] There are also numerous unstable or elusive oxides, such as dicarbon monoxide (C 2 O), oxalic anhydride (C 2 O 4), and carbon trioxide (CO 3).

Three-carbon molecules are based on a skeleton made from three carbon atoms. They may be in a chain, or cycles. C3 hydrocarbons are usually gases, they are inflammable, and may be harmful to humans and the environment. [1] The CAS registry number for three-carbon hydrocarbons is 68606-26-8. Hydrocarbons that include three atoms are: Propane C 3 ...
The valence is the combining capacity of an atom of a given element, determined by the number of hydrogen atoms that it combines with. In methane, carbon has a valence of 4; in ammonia, nitrogen has a valence of 3; in water, oxygen has a valence of 2; and in hydrogen chloride, chlorine has a valence of 1.
