Fractions of crude oil have different properties and uses, affecting the demand for these molecules.
Larger hydrocarbons can be broken down (cracked) to produce smaller, more useful molecules.
Cracking can be done by various methods including catalytic cracking and steam cracking.
The products of cracking include alkanes and alkenes, which have a double bond between two carbon atoms.
Bromine water changes from orange/brown to colourless in the presence of an alkene.
