Topic 4: Introductory Organic Chemistry and Alkanes

4.1—The difference between hazard and risk

4.2—The hazards associated with organic compounds and why it is necessary to carry out risk assessments when dealing

4.3—Suggest ways in which risks can be reduced and reactions carried out safely, for example: i working on a smaller scale ii

4.4—The concepts of homologous series and functional group

4.5—Apply the rules of International Union of Pure and Applied Chemistry (IUPAC) nomenclature to: i name compounds relevant

4.6—Classify reactions as addition, substitution, oxidation, reduction or polymerisation

4.7—Bond breaking can be: i homolytic, to produce free radicals ii heterolytic, to produce ions

4.8—Definitions of the terms ‘free radical’ and ‘electrophile’ 4B: Alkanes Students will be assessed on their ability to:

4.9—The general formula of alkanes and cycloalkanes, and understand that they are hydrocarbons (compounds of carbon and hydrogen

4.10—The term ‘structural isomerism’

4.11—Draw and name the structural isomers of alkanes and cycloalkanes with up to six carbon atoms

4.12—Alkanes are used as fuels and obtained from the fractional distillation, cracking and reforming of crude oil

4.13—Pollutants

4.14—The problems arising from pollutants from the combustion of alkane fuels

4.15—Discuss the reasons for developing alternative fuels in terms of sustainability and reducing emissions

4.16—Apply the concept of carbon neutrality to different fuels, such as petrol, bioethanol and hydrogen

4.17—The reactions of alkanes with: i oxygen in the air (combustion) ii halogens

4.18—The mechanism of the free radical substitution reaction between an alkane and a halogen: i using free radicals, which are
