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).
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).
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).

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.
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 ...
Nitrogen, unlike its neighbor carbon, is much less likely to form chains that are stable at room temperature. But, there do exist nitrogen chains; for example, in solid nitrogen, triazane, azide anion and triazoles. [12] [13] Longer series with eight or more nitrogen atoms, such as 1,1'-Azobis-1,2,3-triazole, have been synthesized. These ...
