One major distinction is between natural and synthetic compounds. Organic compounds can also be classified or subdivided by the presence of heteroatoms, e.g., organometallic compounds, which feature bonds between carbon and a metal, and organophosphorus compounds, which feature bonds between carbon and a phosphorus.

Organic chemistry is a subdiscipline within ... but also containing other elements, [1 ... The source compound is called a monomer. Two main groups of polymers ...
Organic derivatives of the less electropositive main group elements are often robust. Like their derivatives lacking organic substituents, halides and alkoxide ligands for the later organomain group compounds tend to hydrolyze. Organophosphorus and silanes exhibit this pattern: R 3 SiCl + H 2 O → R 3 SiOH + HCl R 2 PCl + H 2 O → R 2 POH + HCl
Organic chemistry is the scientific study of the structure, properties, composition, reactions, and preparation (by synthesis or by other means) of carbon-based compounds, hydrocarbons, and their derivatives. These compounds may contain any number of other elements, including hydrogen, nitrogen, oxygen, the halogens as well as phosphorus ...
Organometallic chemistry is the study of organometallic compounds, chemical compounds containing at least one chemical bond between a carbon atom of an organic molecule and a metal, including alkali, alkaline earth, and transition metals, and sometimes broadened to include metalloids like boron, silicon, and selenium, as well.
The branch of chemistry that studies organic compounds is known as organic chemistry. [15] Carbon is the 15th most abundant element in the Earth's crust, and the fourth most abundant element in the universe by mass, after hydrogen, helium, and oxygen.
Over time, however, scientists learned how to synthesize organic compounds in the lab. The number of organic compounds is immense and the known number of defined compounds is close to 10 million. [4] However, an indefinitely large number of such compounds is theoretically possible. By definition, an organic compound must contain at least one ...
In chemistry and atomic physics, the main group is the group of elements (sometimes called the representative elements) whose lightest members are represented by helium, lithium, beryllium, boron, carbon, nitrogen, oxygen, and fluorine as arranged in the periodic table of the elements. The main group includes the elements (except hydrogen ...
