Definition - What does Organic Compounds mean?
Organic Compounds are a class of complex chemical compounds that contain a carbon atom in their atomic structure. The carbon atom in such compounds can bond with four other atoms which create a complex bonding chain of carbon molecules. The simplest form of organic compound is natural gas or methane that has one carbon atom bonded with four hydrogen atoms with the chemical formula CH4. Hydrocarbons also fall in the category of organic compounds.
Petropedia explains Organic Compounds
The bonding of carbon atoms in an organic compound is based on its bonding style, i.e., it can form single bonds, double bonds and triple bonds with other atoms.
Organic compounds that form single covalent bonds are called alkanes and have the molecular formula CnH2n + 2. If we consider methane, it is an alkane with one carbon atom and four hydrogen atoms. If we place these values in the above formula, i.e., C1H(2x2) + 2 we will get CH4.
Like alkanes, alkenes are also hydrocarbons whose carbon atoms are joined by at least one carbon double bond and have the molecular formula of CnH2n. Ethylene is considered as the simplest form of alkene and has the chemical formula C2H4.
Alkynes are the third type of organic compounds in which carbon atoms are combined by at least one carbon triple bond. These are more complex nature organic compounds. The general formula of alkynes is CnH2n – 2. Acetylene is the simplest form of alkyne and has the chemical formula C2H2.
