Module 1 | Production of materials

Focus 1: Fossil fuels provide both energy and raw materials such as ethylene, for the production of other substances

Lesson 1 | Fossil fuels

  • Identify the industrial source of ethylene from the cracking of some of the fractions from the refining of petroleum

  • Identify that ethylene, because of the high reactivity of its double bond, is readily transformed into many useful products

  • Identify that ethylene serves as a monomer from which polymers are made

  • Identify the following as commercially significant monomers:
    – vinyl chloride
    – styrene
    by both their systematic and common names

  • Describe the uses of the polymers made from the above monomers in terms of their properties

  • Discuss the need for alternative sources of the compounds presently obtained from the petrochemical industry

  • Describe the structure of cellulose and identify it as an example of a condensation polymer found as a major component of biomass

Lesson 2 | Polymerisation reactions

  • Identify polyethylene as an addition polymer and explain the meaning of this term

  • Outline the steps in the production of polyethylene as an example of a commercially and industrially important polymer

  • Explain what is meant by a condensation polymer

  • Describe the reaction involved when a condensation polymer is formed

  • Use available evidence to gather and present data from secondary sources and analyse progress in the recent development and use of a named biopolymer. This analysis should name the specific enzyme(s) used or organism used to synthesise the material and an evaluation of the use or potential use of the polymer produced related to its properties

Lesson 3 | Polymerisation simulation

  • Analyse information from secondary sources such as computer simulations, molecular model kits or multimedia resources to model the polymerisation process

Lesson 4 | Comparing reactivities

  • Identify data, plan and perform a first-hand investigation to compare the reactivities of appropriate alkenes with the corresponding alkanes in bromine water

  • Construct word and balanced formulae equations of chemical reactions as they are encountered
