Term | Definition | Example |
Homologous series | A family or series of Hydrocarbons that have similar chemical properties. | Alkanes Alkenes |
Hydrocarbon | Organic compounds that consist of only Hydrogen and Carbon | Ethanol |
Saturated hydrocarbon | Alkanes (paraffins) - hydrocarbons that have a carbon 'skeleton' or 'back-bone' Hydrogen must have 4 bonds | Methane |
Unsaturated hydrocarbon | Alkenes (olefins) - Hydrocarbons with at least one carbon to carbon double bond. | Ethylene |
General formula | Within a series; it shows the relationship between the number of C atoms and H atoms in the compounds Alkenes - CnH2n. | Hexane C6H14 Propene C3H6 |
Isomerism | Isomers have the same formula but their atoms are arranged differently. Different physical properties | Propane |
