7.3.1 Addition polymerisation Alkenes can be used to make polymers eg poly(ethene) by addition polymerisation In addition polymerization reactions, many small molecules (monomers) join tgt to form large molecules (polymers) Some carrier bags are made from...
7.2.1 Structure and formulae of alkenes Alkenes Hydrocarbons with double C=C bond General formula: CnH2n Why are alkene molecules unsaturated? They contain 2 fewer hydrogen atoms than alkane with same no of carbon atoms What are alkenes used? Produce polymers As...
