What are most substances in crude oil?

Alkanes

2

What is the general formula for an alkane?

CnH2n+2

3

List some uses of hydrocarbons.

petrol, diesel oil, kerosene, heavy fuel oil and liquefied petroleum gases

4

What is fractional distillation?

Heating crude oil to boiling points, then letting it condense at certain points

5

What happens as the chains get longer?

They get more viscous, boiling point increases and it becomes less flammable

6

What is cracking?

Turning hydrocarbons into shorter, more useful alkenes

7

What is the general formula for an alkene?

CnH2n

8

How can we test for an alkene?

Add bromine water, if it goes colourless it is an alkene

9

Are alkenes saturated or not?

They are unsaturated
