Alkanes are Hydrocarbons
- Hydrocarbon are molecules that are made up of Hydrogen and Carbon atoms ONLY.
- Need to know the names and the displayed formulas of the first five alkanes.
Methane-CH4, Ethane-C2H6, Propane-C3H8, Butane-C4H10, Pentane-C5H12

Alkanes are a Homologous Series
- It is a group of compunds that can all be represented by the same general formula.
- Alkanes= CnH2n+2
- No more atoms can join onto the carbon atoms so Alkanes are saturated.
Complete Combustion
- Where there is alot of Oxygen about Alkane burns to produce Carbon Dioxide and Water
- Alkane+Oxygen=Carbon Dioxide+Water
- The gas burns with a clean blue flame.
