Definition of Organic Compound

Organic compounds are the molecules which belong to such a class of chemical compounds that are constituted of one or more than one atom of carbon. The atoms of carbon are linked to each other and some other atoms like hydrogen, nitrogen, or oxygen by covalent bonds. The ability of carbon to form long chains (catenation) is the main reason behind the presence of millions of organic molecules.


The study of the physical and chemical properties, structure and reactivity, and synthesis of these compounds is done under the branch of chemistry known as organic chemistry. The simplest organic compound found in nature is methane CH4. All biological compounds as an example, such as proteins, carbohydrates, and lipids, etc. are also organic.
