Description
The purpose of this CS262 module is the development of manipulative and observational skills through experimental procedures in multistage organic syntheses and utilising a wide range of spectroscopic methods. Experience and application of spectroscopic methods to routine product examination. A reinforcing of the understanding and knowledge of various aspects of the 2nd year organic lectures. A special emphasis will be placed on reaction mechanisms and interpretation of spectra using infra-red and 1H NMR spectroscopy. The experiments will be written up and dated on a hardback notebook in the laboratory and typed experimental reports will be submitted later.

Learning Outcomes
1. Perform basic and advanced synthetic organic chemical and analytical laboratory experiments.
2. Use a range of chemistry and analytical laboratory instrumentation. Analyse the experimental data and write a comprehensive laboratory report discussing the importance and relevance of the experimental results.
3. Illustrate the inorganic chemical reactions with the appropriate REACTION MECHANISM and comprehend the chemical reactions undertaken in each experiment.
4. Discuss the chemical reactions and illustrate comprehensively the reaction mechanisms for the experiments.
5. Understand and adhere to fully the health and safety guidelines and rules in the chemical laboratory.
6. Fully understand the implications of plagiarism in writing up of experimental notebooks and reports.
7. Analyse and interpret the infra-red and NMR spectra (1H, 13C) for simple organic molecules

Indicative Content and Learning Activities
CHEMISTRY LABORATORY EXPERIMENTS.
SYNTHESIS. A number of synthetic chemistry experiments will be undertaken. These are intended to illustrate relevant and interesting aspects of theory and techniques. Some examples include:1. Conversion of acetanilide to sulphanilamide via the intermediacy of 4-acetamidobenzene sulphonamide; diazo couplingof sulphanilamide with 2-naphthol. 2. Conversion of benzaldehyde to stilbene via the intermediacy of 1,2-diphenylethanol using Grignard reagent; crossed aldol condensation of benzaldehyde and acetone. 3.Oxidation reactions, for example cyclohexanol to cyclohexanone; steam distillation; adipic acid formation. 4.Reduction reactions, for example, reduction of benzoin obtained from benzoin condensation, reduction of benzil, borohydride reductions. 5. Electrophilic aromatic substitution, e.g. Friedel-Crafts alkylation, benzypyridine nitration to give a photochromic material, Sandmeyer reaction, e.g. anthranilic acid to o-iodobenzoic acid. 6. Protection and deprotection groups in organic syntheses. 7. Malonic ester chemistry. 8. Preparation of E,Z-stilbenes using the Wittig reaction: use of flash chromatography. 9. Preparation of dimedone and derivatives/recrystallisation techniques. QUALITATIVE ORGANIC ANALYSIS. Precise identification of a number of unknown organic substances using combinations of screening tests,confirmatory tests for functional groups, derivative formation and spectroscopic analysis..
