- Hydrocarbons and polymers
- Alkanes(saturated hydrocarbon)
- carbon is bonded to 4 other atoms and are all single bonds
- click arrow to see a diagram
- examples of theses are ethane and propane and butane
- they are unreactive but burn well

- Testing for alkanes and alkenes
- Alkenes (unsaturated hydrocarbon)
- similar to alkanes but the carbons have a double covalent bond and there for less hydrogen's
- examples of these are ,ethene, propene and butene

- the addition of bromine water
- bromine water is a clear orange (iron brew)
- when and alkene is added to the bromine water it will become colourless
- when an alkane is added the bromine water will stay a clear ornage

- cracking
- the breaking down of long chain hydrocarbons into more useful short chain molecules
- this can help meet demands
- the moelcoles are cracked by being heated up until vaporised.
- this is thermal decomposition
- to make this process fater aluminium oxide is heated up and used as a catalyst

- Polymers
- long chain hydrocarbons are sometimes polymers made up of monomers
- monomers are short chain unsaturated hydrocarbon molecules
- addition polymerisation is when alkenes join together without producing another substance
- after they have polymerised the polymer is saturated
- formula for addition polymerisation

- uses of of poymers
- poly(propene) PP has a good chemical resistance and is flexible
- chairs, stationary, ropes, crates, bottles, clothing
- poly(chlorehrene) PVC good impact resistance and can be rigid or flexible
- flooring,double glazed window frames, pipes, clothing, cable covering, electrical components
- PTFE water resistant flexible and non -stick
- non-stick cookware coating, lubricant sprays, waterproof coating
- Poly(ethene) PE has a good chemical resistance and is flexible
- food covering,bins, water pipes, bags, bottles, food trays
- poly(propene) PP has a good chemical resistance and is flexible
- disposal of polymers
- burning
- this causes air pollution and some shouldn't be burnt because they release toxic fumes
- landfill
- waste builds up as they aren't biodegradable so will not decompose
- recycling
- some polymers can be made into another orm really easily which will reduce the demand to make new ones
