2. Name as many substances as you can that are made from carbon atoms

2. Organic chemistry is the study of carbon compounds.
It includes the study of synthetic compounds – polymers, drugs and dyes.

3. Carbon can form chains, branched chains and rings.

4. A hydrocarbon is a compound containing only ___________ and __________.
Crude oil is mixture of hydrocarbons.
Most of them are called alkanes.

5. Complete the rest of the table
Molecular formula
Structural formula
Name
CH4
C2H6
Methane
Ethane
Propane
Butane
Pentane
Hexane
The general formula for alkanes is CnH2n+2
Complete the rest of the table

6. Alkanes have different properties.
Small hydrocarbons have lower boiling points than larger ones.
How can the different alkanes be separated from Crude oil?
The C-C and C-H bonds in alkanes do not react with common aqueous reagents like acids so are unreactive.

7. Carbon Chemistry
What is fractional distillation? How does it work? What physical property does it rely on?

8. Questions: a) In which group of the periodic table does carbon belong?
b) How many electrons are there in the outer shell of a carbon atom?
c) Which groups in the periodic table include elements that form simple ions?
d) Is carbon likely to form simple ions (charged particles)?
Give an example which show that alkanes, or mixtures of alkanes, do not mix with water.
Are the alkanes in petrol (C8H18) more or less dense than water?
Write a balanced equation for propane burning in plenty of air.
Write a balanced equation for methane burning in a limited supply of air (two products)
