This lesson presentation looks at the carboxylic acids and focuses on the names, displayed formula, chemical formulae and reactions of this homologous series. The lesson begins with a bit of fun which gets enables the students to recognise that the functional group is COOH. A step by step guide is used to show the students how to draw the displayed formula for ethanoic acid, using the functional group before they apply their knowledge to draw the remaining acids in the first four. This series are connected by a general formula and students are shown how it is worked out for the alkanes and the alkenes so that students can work it out for the acids. Moving forwards, the reactions of these acids is shown and related to the reactions of acids that was previously learnt. Students will recall how to write the name of the salt and the balanced symbol equation.
