Unsaturated hydrocarbons are hydrocarbons that have double or triple covalent bonds between adjacent carbon atoms. Those with at least one carbon to carbon double bond are called alkenes and those with at least one carbon to carbon triple bond are called alkynes.
Types of hydrocarbons. A hydrocarbon can exist as a gas (propane or methane), liquid (benzene or hexane), waxes or low melting solids (like naphthalene) or polymers (like polyethylene). There are four types of hydrocarbons namely saturated hydrocarbons, unsaturated hydrocarbons, cycloalkanes and aromatic hydrocarbons.nsaturated hydrocarbon Hydrocarbons having one or more double or triple bonds between carbon atoms are called unsaturated hydrocarbons. Alkenes are the hydrocarbons that have one, double bond between the carbon atoms. On the other hand, those that contain triple bonds are alkynes.
