- Alkanes
- Structure, Naming and Properties
- Saturated hydrocarbons contain single bonds only.
- The general formula for alkanes is CnH2n+2
- Naming alkanes
- Identify the longest continuous carbon chain
- Identify and name branches
- eg. CH3 : methyl
- number the chain in both directions and pick the scheme that has the lowest possible positions
- 2 of the same branch - di
- Structural isomers have the same molecular formula but different structural formulas.
- Alkanes as fuels
- Fuels need to be: readily available, easily transportable and inexpensive.
- Crude oil is formed through heat and pressure on plant/animal remains
- This is a long process and takes millions of years, therefore it is a non-renewable resource
- Fractional distillation is the seperation of the compounds in a liquid micture into fractions which differ in boiling point
