Making Polymers

Includes information on hydrocarbons and polymerisation.

What is a hydrocarbon?
A hydrocarbon is a compound made of only hydrogen and carbon atoms.
1 of 10
What are alkanes?
An alkane is a hydrocarbon that only has single covalent bonds.
2 of 10
What are alkenes?
An alkene is a hydrocarbon that has at least one double covalent bond.
3 of 10
How can we test if an alkene is present?
Alkenes decolourise bromine water.
4 of 10
Why do alkenes decolourise bromine water?
The alkene and the bromines form a new compound by an addition reaction. A dibrimo compound forms and this is colourless.
5 of 10
What is a saturated compound?
A saturated compound has only single covalent bonds between carbon atoms.
6 of 10
What is an unsaturated compound?
An unsaturated compound has at least one double covalent bond between its hydrogen atoms.
7 of 10
What conditions are needed for an addition polymer reaction to take place?
High pressure and a catalyst.
8 of 10
What is the process of polymerisation?
Polymerisation is the process whereby many alkene monomers are reacted to form a polymer.
9 of 10
What is the process of polymerisation?
Polymerisation reactions require high pressure and a catalyst.
