2. What’s in a medicine?: Week 1 Spec points describe the following reactions involving carbony compounds (aldehydes and ketones): formation of carbonyl compounds by oxidation of alcohols using acidified dichromate with the need to distil in the case of aldehydes (synoptic); oxidation of aldehydes to carboxylic acids using acidified dichromate, under reflux; reaction with hydrogen cyanide to form the cyanohydrin describe the mechanism of the nucleophilic addition reaction between a carbonyl compound and hydrogen cyanide, using ‘curly arrows’ and bond polarities Key learning activities WM 2.1 Extraction of an active chemical from willow bark WM 2.2 Nucleophilic addition mechanism Chemical ideas 13.7 Aldehydes and ketones Recap 13.2 Alcohols and ethers Chem Idea Problems p. 319 Problems 13.7 Nos 1 to 6.

3. What’s in a medicine?: Week 2 Spec points recognise and write formulae for members of the following homologous series: diols, diamines, dicarboxylic acids, phenols, acyl chlorides, acid anhydrides, esters describe and explain the acidic nature of carboxylic acids, and their reaction with alkalies and carbonates describe the reaction of alcohols with carboxylic acids in the presence of concentrated sulfuric acid or concentrated hydrochloric acid to form esters describe the following properties of phenols: acidic nature, and their reaction with alkalis but not carbonates; test with neutral iron(III) chloride solution, to give a purple colouration; reaction with acyl chlorides to form esters Key learning activities WM 1Investigating the chemistry of the – OH group in phenols and carboxylic acids WM 4 Using spectroscopy Chemical ideas 13.3 Carboxylic acids and their derivatives 13.4 The – OH group in alcohols, phenols and cacids 6.5 Mass spec (section on interpreting spectra for compounds and fragments Recap Infrared spectroscopy Chem Idea Problems p. 302 Nos 1 to 5 P306 Nos 1 to 6 P144 Nos 3 to 5 Advance warning WM3benzoyl chloride Salters spec Storyline WM 3 Identifying the active chemical in willow bark WM 4 Instrumental analysis Events Last check on re-takes.
