List some uses of hydrocarbons.
petrol, diesel oil, kerosene, heavy fuel oil and liquefied petroleum gases
What is fractional distillation?
Heating crude oil to boiling points, then letting it condense at certain points
What happens as the chains get longer?

What is cracking?
Turning hydrocarbons into shorter, more useful alkenes
What is the general formula for an alkene?
How can we test for an alkene?
Add bromine water, if it goes colourless it is an alkene
Are alkenes saturated or not?
