Cycloalkanes are a type of hydrocarbon that consists of carbon atoms arranged in a ring structure. They are saturated compounds, meaning they contain only single bonds between the carbon atoms. Common examples include cyclopropane, cyclobutane, and cyclohexane, each named for the number of carbon atoms in the ring. These compounds are important in organic chemistry and can be found in various natural and synthetic substances. Cycloalkanes have unique properties, such as higher boiling points compared to their straight-chain counterparts, due to their cyclic structure. They are often used in fuels and as solvents in industrial applications.
