- Hydrocarbons
- Hydrocarbons contain only hydrogen and carbon atoms
- Alkanes
- Alkanes are a Homologous series
- Have only single covalent bonds
- The first four alkanes are methane, ethane, propane and butane
- General formula = C n H 2n+2
- Properties
- main properties: viscosity, boiling point, ability to ignite and number of carbon atoms
- Shorter hydrocarbons are more runny (less viscous)
- Shorter hydrocarbons are more volatile (lower boiling points)
- Less carbon atoms makes them more flammable (easier to ignite)
- Short chains have less carbon atoms
- main properties: viscosity, boiling point, ability to ignite and number of carbon atoms
- Complete combustion
- hydrocarbon + oxygen = carbon dioxide + water (+ energy0
- The hydrogen and carbon in the hydrocarbon are oxidised
- Hydroc's are used as fuel due to the amount of energy they release through combustion
