- Chemistry part 2
- hydrocarbons are cracked passing them over a heated catalyst.
- alkenes are produced. they have a double bond and is an unsaturated hydrocarbon.
- Useful for making other molecules, like polymers.
- small alkene molecules join together to from polymers. This is polymerisation
- Polymers can be used to make waterproof items. plastic bottles, ropes and casings for electrical appliances.
- it is cheap and easy to produce
- Plastics aren't biodegradable and this leads up to the build up of plastic waste in landfill sites.
- Ethanol can be produced by the hydration of ethene with steam in the presence of a catalyst.
- Ethanol can also be produced by fermentation with yeast.

- Disadvantages of crude oil
- causes pollution
- increases global warming
- oil spills damage the environment
