Cycloalkane

Cycloalkanes are a class of organic compounds that contain a closed-ring structure composed entirely of carbon atoms. They are also known as cyclic hydrocarbons or naphthenes. The simplest example of a cycloalkane is cyclopropane, which has three carbon atoms arranged in a triangle.

Cycloalkanes have the general formula CnH2n, where n is the number of carbon atoms in the ring. They can range in size from three carbons (cyclopropane) to many thousands of carbons in natural products such as rubber and asphalt.

Cycloalkanes are typically less reactive than their open-chain counterparts (alkanes) due to the strain imposed by the cyclic structure. They are mostly found in petroleum and natural gas, and some commercially important cycloalkanes include cyclohexane, used as a solvent, and cyclooctane, used as a starting material for the synthesis of various organic compounds.
