What is crude oil and natural gas made from?
The dead remains of marine organisms
1 of 7
Why does distillation work?
Because the liquids have different boiling points
2 of 7
Small hydrocarbons...
have a low boiling point and are gaseous
3 of 7
During fractional distillation...
substances with high boiling points condense at the bottom and substances with lower boiling points condense at the top
4 of 7
What is cracking?
Breaking large hydrocarbons into smaller, more useful hydrocarbons as well as an alkene, which is used for polmerisation
5 of 7
Why do large hydrocarbons have high boiling points?
As there are more weak intermolecular forces between the hydrocarbon molecules that are needed to be broken, more thermal energy is needed to break these forces thus giving it a high boiling point
6 of 7
