1

What are the products of cracking

Alkanes and unsaturated hydrocarbons called alkenes

2

What happens when alkenes react with bromine water

Turn it from Orange to colourless

3

What does the process used to crack hydrocarbons to produce smaller more useful molecules involve

Heating the hydrocarbons to vaporise them
The vapours are passed over a hot catalyst or mixed with steam and heated to a very high temp
So that thermal decomposition occurs
