Flashcards in Crude Oil Deck (25):
1

Isomer

Same molecular formula, different structure

2

Unsaturated

Compounds that have double bonds

3

Saturated

Only contain single bonds

4

Alkanes

CnH2n+2
Saturated
Single bonds

5

Alkenes

CnH2n
Unsaturated
Double bonds

6

Saturation experiment for Alkene

Add bromine water
Brown --> colourless

(stay brown in alkane)

7

Hydrocarbon

Compound that contains hydrogen and carbon ONLY

8

Homologous series properties

1- Trend in physical properties
2- Similar chemical properties

9

Explain how fractional distillation can be used to separate crude oil.

1- Different hydrocarbons have different oiling points so crude oil can be separated into fractions
2- The crude oil is heated and vaporised and passed into the fractioning column
3- The fractioning column is hotter at the bottom and cooler at the top
4- The vapour rises and the hydrocarbon condenses when it reaches it's boiling point.

10

How does the length of the molecules in the fractions chance as you go up the column?

The length of the molecules decrease in the fractions as you go up the fraction column

11

What are conditions for carrying out cracking?

Heating the substance (aluminium/silica) at 600-700°

12

Volatility

How easy something can turn into a gas

13

Flammability

How easy something catches fire

14

Viscosity

Thickness of water

15

What is Crude oil?

mixture of hydrocarbons

16

What does incomplete combustion of fuels produce?

carbon monoxide, which is poisonous because it reduces the capacity of the blood to carry oxygen

17

Order of Gasses in Fractional Distillation

Refinery Gas
Gasoline
Kerosine
Diesel
Fuel oil
Bitumen

18

What is Refinery Gas used for?

Heating and Cooking

19

What is Gasoline used for?

Fuel for cars

20

What is Kerosine used for?

Fuel for planes

21

What is Diesel used for?

Fuel for trains/trucks

22

What is Fuel oil used for?

Fuel for ships

23

What is Bitumen used for?

To make Tar for roads

24

Where is it most viscous?

At the bottom

25

Where is the highest boiling point?

At the bottom
