| Term | Definition |
|---|
| Alkanes | hydrocarbons containing only single C-C bonds |
| CnH2n+2 | General formula for alkanes |
| Homologous series | A family of hydrocarbons where each member differs form the other by -CH2 |
| Alkenes | hydrocarbons containing one C to C double bond |
| CnH2n | General formula for alkenes |
| dispersion forces | The forces holding hydrocarbon molecules to each other. Increase with increasing molecular mass |
| Cracking | where larger hydrocarbons are broken down to smaller hydrocarbons |
| Ethene ( C2H4) | the smallest alkene, building block for polymers |
| combustion | when a hydrocarbon is burnt in oxygen ( forms CO2 and H2O if enough oxygen is present) |
| substitution reaction | where one of the H atoms in a Hydrocarbon is replaced by another atom or group of atoms |
| addition reaction | where an atom ( or group) is added across an alkene and a saturated compound is formed |
| Saturated Hydrocarbon | a Hydrocarbon that contains only singe C-C bonds |
| functional group | an atom or group of atoms added to a Hydrocarbon and make it more reactive |
| alkanols | R-OH, a family of hydrocarbons with an hydroxyl (OH) functional gorup |
| alkanoic acid | R-COOH carboxylic acids , ( contain a C=O and -OH) |
| covalent bonding | the bonding within hydrocarbon compounds |
