Cyclohydrocarbons: Structural Formulas

Cyclohydrocarbons are the cyclic, or ring, analogues of the alkanes, alkenes, and alkynes. These hydrocarbons are often referred to as alicyclic compounds, and the simplest class is made up of the cycloalkanes. Their general molecular formula is C n H 2 n , where n equals any whole number of 3 or greater. Normally, these compounds are represented by geometric figures.
