C1d-making Polymers Flashcards
(11 cards)
What is saturated compound?
A compound that only contains single covalent bonds between carbon atoms
What is an unsaturated compound?
A compound that contains at least one double covalent bond between carbon atoms
What are alkanes?
Saturated hydrocarbons
What are alkenes?
Unsaturated hydrocarbons
What do double bonds involve?
Two shared pairs of electrons
What is the test for an alkene?
Alkenes turn bromine water from orange to colourless
Addition reaction
Bromine adds to double bond
Formation of a colourless dibromo compound
How do you form the name of a polymer?
Poly+ monomer
What is a hydrocarbon?
A compound formed between carbon atoms and hydrogen only
What are polymers?
Long chain molecules made from many small molecules. Called monomers
What does addition polymerisation need?
High pressure
Catalyst
What is addition polymerisation?
When lots of unsaturated monomer molecules(alkenes) open up their double bonds and join together to form polymer chains
