Organic chemistry
Code: G290I-
Teacher:  Angela Bassoli
CFU subdivision: Lectures: 6
Practices in classroom: 1
Practices in laboratory:  1
Basic aims:  Objective of the course is to give basic information on theoretical and experimental aspects of organic chemistry, in particular for classes of compounds important in food sciences and technologies.
Acquired skills:  Understanding of chemical formulas; knowledge of functional groups; properties and reactivity of organic compounds; importance of organic compounds in food; fundamental operations in manipulations of organic compounds.
Course contents:  Structure, physico-chemical properties, synthetic methods and reactivity of the amin classes of organic compounds. Organic chemistry laboratory: fundamental operations in purification, separation and recognition of organic compounds.
Program:  Organic compounds are the basis for living organisms. 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. Carbon atom: hybridisation, structure of sigma and pi covalent bonds. 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. Alkanes and cycloalkanes; conformation analysis; properties; radical reactions and stability. Alkenes: structure, properties; cis-trans isomerism; dienes and polyenes; electrophyilic additions; radical reactions; polymerisation. Aromatic hydrocarbons and heterocyclic compounds: structure, nomenclature. Halogenated hydrocarbons: structure, properties; nucleophylic substitution and elimination reactions. Alcohols: structure, properties, natural sources; reactivity. Phenols: acido-base and redox properties: Natural phenols and polyphenols. Other oxygenated compounds: ethers, epoxides, quinones. Sulphurated compounds: thiols and disulphides. Chirality and optical activity: enantiomers and diastereoisomers; absolute and relative configuration; mesoforms, racemates. Carbonylic compounds: aldehydes and ketones. Structure, properties. Nucleophilic addition and redox reactions. Hydrated, acetals and ketals. Nucleophilic addition of nitrogen compounds. Ketoenolic tautomery. Carbohydrates. Monosaccharides: structure, open and cyclic forms; Fisher projections, stereochemistry; mutarotation. Glycosides. Di- and polysaccharides: properties, reactions, importance in food. Carboxylic acids: structure, reactions. Carboxylic derivatives: esters, anhydrides, acylic halogen derivatives; amides, carbamates, ureas. Acylic substitution reactions: ester formation; esters and amides hydrolysis. Lipids: fatty acids, triglycerides, fosfolipids. Soap and tensioactives. Nitrogen derivatives. Amines: structure, properties, rections. Natural nitrogen compounds: alkaloids, porphyrines, nucleic acids. Aminoacids: the peptide bond; peptides and proteins. Organic chemistry laboratory. Fundamental opeartions in purification, separation and recognition of organic compounds. Crystallisation, melting point detemination. Simple, fractional and vacuum distillation techniques. Column and thin layer chromatography. Filtration techniques. Liquid-liquid extraction, anhydrification, reduced pressure evaporation.
Prerequisites:  Basic concepts: atomic and molecular weight; mole; valence; ionic and covalent bonds; intermolecular bonds; electronegativity; polarity; state transitions; equilibrium; equilibrium constant; acid-base reactions; redox reactions; oxidation number.
Preparatory instructions:  General chemistry and physical chemistry exam is highly recommended.
Learning materials:  Organic chemistry at university level. Examples: Brown, Campbell, Farrel, Elementi di Chimica Organica, EdiSES (with exercise book) and molecular models ; the slides used by the teacher during lessons will be made available at: http://ariel.ctu.unimi.it/corsi/chimOrgAgraria/home/
Other info:  To partecipate to laboratory exercitations the student must follow a lesson on safety procedures and sign declaration. Usually laboratory lesson starts 2 or 3 weeks after the beginning of the course and the time table will be give during lessons and published on the online site.
Examination consists in a written test; the student will solve problems similar to those proposed during exercitations and answer to theoretical questions.
The teacher is available for individual colloquium, please write an email to make a reservation.
