When a hydrocarbon chain has a double bond it's called an ________. AlkEne
Double bonds have two shared pairs of ________. Electrons
AlkEnes are described as being... Unsaturated
To test for alkEnes you can use... Bromine water
What are more than one monomer called? Polymers
When alkenes join together making a polymer, the reaction is called _______________. Polymerisation
The process of polymerisation needs 1) 2) High pressure Catalyst
Atoms in a plastic are held together by ___________ bonds. Covalent
Plastics that have WEAK intermolecular forces have... 1) 2) Low melting points Can be stretched easily because the polymer molecules can slide over each other
