Introduction
Bayani Gaba-gaba
Carbon is unique among the elements. It can form four strong covalent bonds and chain itself into molecules of almost unlimited size and variety, from the methane in natural gas to the DNA in your cells. Organic chemistry is the study of these carbon-based compounds, and it underpins pharmaceuticals, plastics, fuels, and food science.
In this lesson you will learn what defines a hydrocarbon, how to represent organic molecules using different types of formulae, what homologous series, functional groups and isomerism mean, and how to name compounds using IUPAC rules. These foundations are essential for every organic topic that follows in the Edexcel specification.
Manufura
- know that a hydrocarbon is a compound of hydrogen and carbon only
- understand how to represent organic molecules using empirical formulae, molecular formulae, general formulae, structural formulae and displayed formulae
- know what is meant by the terms homologous series, functional group and isomerism
- understand how to name compounds relevant to this specification using the rules of International Union of Pure and Applied Chemistry (IUPAC) nomenclature students will be expected to name compounds containing up to six carbon atoms
- understand how to write the possible structural and displayed formulae of an organic molecule given its molecular formula
- understand how to classify reactions of organic compounds as substitution, addition and combustion knowledge of reaction mechanisms is not required
