C1d: Making Polymers Grade E Grade C Grade A Key Information Hydrocarbons are compounds made from carbon and hydrogen atoms joined by covalent bonds. Alkanes are saturated - they have only single bonds. Alkenes have a double bond - they are unsaturated. Alkenes react with brown bromine water and decolourise it, but alkanes do not. Alkenes can act as monomers. Under high pressure and in the presence of a catalyst many monomer molecules join together to make polymer molecules. These polymer molecules are saturated. Revision Make a card game using the diagrams of different alkanes and alkenes and their names Create a revision card on polymerisation
