This course will describe structure, phisico-chemical properties and reactivity of the main classes of organic compounds, with particular emphasis for those important in food. W1: introduction. Carbon atom: hybridisation, structure of sigma and pi covalent bonds. W2: Organic compounds: structure, isomeric forms, use of compact and extended formulas. Alkylic groups; functional groups. Intermolecular forces in organic compounds and their relationship with physical properties. W3: Alkanes and cycloalkanes; conformation analysis; properties; radical reactions and stability. W4: Alkenes: structure, properties; cis-trans isomerism; electrophyilic additions; radical reactions; polymerisation. W5: dienes, polyenes and delocalised systems. Aromatic hydrocarbons and heterocyclic compounds: structure, nomenclature. Cromophores and colour. W6: halogenated hydrocarbons: structure, properties; nucleophylic substitution and elimination reactions. W7: Stereochemistry. Chirality and optical activity: enantiomers and diastereoisomers; absolute and relative configuration; mesoforms, racemates. W8: Alcohols: structure, properties, natural sources; reactivity.
