1 Alkanes are Saturated Hydrocarbons. 2  They consist of the elements Carbon and Hydrogen, and all the bonds between the Carbon atoms are single bonds. 3  They have the general formula CnH2n+2.4  Since all Alkanes are similar in structure and properties, they are called a Homologous Series. Alkanes are Saturated Hydrocarbons. 2  They consist of the elements Carbon and Hydrogen, and all the bonds between the Carbon atoms are single bonds. 3  They have the general formula CnH2n+2.
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.ycloalkanes These are hydrocarbons that have one or more carbon rings. These rings have hydrogen atoms attached to it. Aromatic hydrocarbons These hydrocarbons have a stable structure and they have one aromatic ring. An example of one of the simplest aromatic hydrocarbons is benzene. These are also known as Arenes.
