1/CH/A1 Chemistry A1 Aim: To serve as a revision of the organic chemistry previously covered at A-level and to provide an introduction to the general areas of functional group chemistry (particularly the carbonyl group), nomenclature and mechanism. Intended outcomes Students should be able to: name simple organic compounds and to write molecular formulae from given names; identify suitable reagents for selected organic reactions and describe their mechanisms using curly arrows carry out simple organic preparations in the laboratory. Content: L M Harwood (4 lectures) Foundations of Organic Chemistry. Introduction to atomic structure, orbital and hybridisation electron accounting, drawing structures, representing electron movement, bonding in alkanes, alkenes, alkynes and aromatic molecules. L M Harwood (3 lectures) Nomenclature: how to name organic compds according to IUPAC rules A Gilbert (10 lectures) Basic principles of organic chemistry; structure and bonding; the use of curly arrows; electron distributions and reactivity; reactive species. Mechanistic principles in organic chemistry. Isomeric structures. Reactions of ethenes: addition of hydrogen, hydrogen halides, and halogens; Markovnikov, anti-Markovnikov, radical reactions, hydroboration; epoxide formation, ozonolysis, and diol formation. Chemistry of alkynes, hydrogenation to give Z-alkenes. Outline of cycloaddition process. Aromatic chemistry: electrophilic attack, acylation, alkylation, sulphonation, etc. J E McKendrick (12 lectures) Carbonyl Chemistry. Classification according to chemical reactivity: examples of industrially important compounds. Reactions of carbonyl compounds with nucleophilic reagents; reactions with reducing reagents; Grignard reagents; hydroxylamine and hydrazines; acetal formation and its role in protection. Methods for removing carbonyl groups. Conjugate addition to ,-unsaturated compounds. Keto-enol tautomerism and acid-base reactions. Chemistry of carboxylic acids and derivatives: illustrative examples from natural product chemistry. F J Davis (8 lectures) Application of Functional Group Chemistry.

TEACHING AND LEARNING METHODS: Factual information will be given in lectures which will be supplemented by regular tutorials, workshops and appropriate practical work. Students will be expected to have read the relevant sections of J Claydon, N Greaves, S Warren, W Wothers, Organic Chemistry, in their own time.
