Learning intentions That organic chemistry is the chemistry of carbon That alkanes are a homologous series of hydrocarbons with a general formula C n H 2n+2 That alkanes may form straight or branched molecules, and these are called isomers That our written work is legible That we can locate and use information from the reference book Advanced Chemistry for You That the products of combustion of alkanes are carbon dioxide and water

Carbon Carbon forms the basis of all organic molecules. Organic molecules are found in living things (organisms) e.g. amino acids, DNA, proteins, fats, carbohydrates, enzymes etc ‘organic’ means it contains carbon Organic chemistry is the chemistry of carbon
