Cracking Crude Oil Flashcards
1
Q
What are the products of cracking
A
Alkanes and unsaturated hydrocarbons called alkenes
2
Q
What happens when alkenes react with bromine water
A
Turn it from Orange to colourless
3
Q
What does the process used to crack hydrocarbons to produce smaller more useful molecules involve
A
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
