Definition of hydrocarbons: Hydrocarbons are chemical compounds that are formed from only hydrogen atoms and carbon atoms. Categories of hydrocarbons include: 1  Alkanes - *saturated hydrocarbons, only single bonds. 2  Alkenes - *unsaturated hydrocarbons, include a double bond.aturated fatty acids have at least one double bond. Hydrocarbons can be classified as saturated or unsaturated. School-level (e.g. GCSE) chemistry often requires students to be able to give examples of saturated and unsaturated hydrocarbons and to describe their molecular structures in the form of molecular diagrams.
