Classification of Organic Compounds

A general classification of the organic compound on the basis of structure is described in the below image.

Organic compounds based on their structure are broadly categorized as:

  • Open-Chain Compounds or Acyclic Compounds.
  • Closed-Chain Compounds or Cyclic Compounds.

Classification of Organic Compounds

Organic compounds are defined as chemical compounds which contain carbon atoms linked with other elements through simple covalent bonds. These elements could be connected by single covalent bonds, double covalent bonds, or triple covalent bonds. In other words, we can say that all organic compounds contain carbon as their central atom. We must note that all compounds containing carbon are not considered organic compounds, such as carbonates(-CO3), bicarbonates(-HCO3), etc are carbon-containing compounds but not organic. Whereas we can say with surety that all organic compounds contain carbon atoms but vice versa is not true.

In this article, we will learn about organic compounds and their various classification based on bonds, functional groups, and structure. As there are millions of organic compounds and studying them individually is not possible. Therefore, the classification of organic compounds is required. So, let’s start learning about Organic Compounds and their classification.

Organic Compounds

Organic Compounds are those chemical compounds that are majorly derived from livings beings. The branch of chemistry which deals with the study of organic compounds is called Organic Chemistry. The most significant feature of an Organic Compound is that it contains Carbon atoms but not all compounds that have Carbon atom is organic in nature. For Example, CO and CO2 are not organic in nature. Hence, in order to identify an Organic Compound, we must look that if it contains an open or closed chain of Carbon atoms with hydrogen atoms linked to it or any other atom in place of hydrogen. For Example, CH4 and CCl4 both are organic in nature....

What is an Organic Compound?

Organic compounds are compounds that are produced by living organisms. They are very useful in all living organisms’ reproduction, development, and working. Organic Compounds have special characteristics, in that they all contain carbon atoms. Carbon has a special property called catenation property which helps it to form long-chained compounds. Carbon has four electrons in its outermost shell so it can form four covalent bonds to complete its octet. Carbon forms covalent bonds with other carbon atoms along with it also form bonds with Hydrogen, Nitrogen, Oxygen, and other atoms....
