WebThe cycloalkane molecule is a closed chain (ring). The cycloalkane series begin with cyclopropane C 3 H 6, followed by cyclobutane, cyclopentane, etc. Detailed information on the structure and chemical properties of cycloalkanes is presented in Ref. [4].The three main types of naphthenes are shown in Fig. 1.6. In organic chemistry, the cycloalkanes (also called naphthenes, but distinct from naphthalene) are the monocyclic saturated hydrocarbons. In other words, a cycloalkane consists only of hydrogen and carbon atoms arranged in a structure containing a single ring (possibly with side chains), and all of the carbon-carbon bonds are single. The larger cycloalkanes, with more than 20 carbon atoms ar…
