Making Polymers Includes information on hydrocarbons and polymerisation. 0.0 / 5 ? ChemistryMaking PolymersGCSEOCR Created by: Simikatheryn.xCreated on: 08-06-16 20:11 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. 10 of 10
