The Ring Carbons can be arranged in a ring, such as cyclobutane. Unsaturated Hydrocarbons A hydrocarbon that contains one or more double or triple bonds is an unsaturated hydrocarbon. There are three types of unsaturated hydrocarbons alkenes, alkynes, and aromatic hydrocarbons.Alkenes Many fruit bearing plants produce ethene, which controls the rate at which fruits ripening. Alkynes Alkynes are the most reactive hydrocarbon compounds.here are three types of unsaturated hydrocarbons alkenes, alkynes, and aromatic hydrocarbons.
