What is crude oil a mixture of?
Different hydrocarbons
1 of 11
How are the different hydrocarbons separated?
Fractional distillation
2 of 11
Do longer hydrocarbons have higher or lower boiling points?
Higher. Drain out of column early
3 of 11
Do shorter hydrocarbons have higher or lower boiling points?
Lower. Drain out of column near the top
4 of 11
Is the fractionating column hottest at the top or bottom?
Bottom.
5 of 11
What 4 things happen as the size of the hydocarbons increase?
Boiling point increases, less flammable, volatility decreases, more viscous
6 of 11
What are the two important bonds in crude oil?
Stong covalent bonds and intermolecular forces
7 of 11
What is cracking?
Spitting up long-chain hydrocarbons into smaller alkane and alkene molecules
8 of 11
What is cracking a form of?
Thermal decomposition
9 of 11
What conditions are needed for cracking?
Extremely hot (about 400-700 degrees) and a catalyst
10 of 11
What does cracking help to do?
Match supply with demand
