85325 - CHIMICA

Learning outcomes

At the end of the course the student will acquire basic knowledge on the structure of matter and on kinetics and thermodynamics principles regulating its transformation. The student will also be able to understand, from the molecular point of view, the chemical reactions occurring in biosphere and all relationship among structure, properties and reactivity of organic molecules. The student will be able to critically analyze information concerning ecosphere, and will own basic knowledge for understanding the biochemistry, biology, genetic and physiology courses and to proceed with single activities in food technology.

Course contents

The course is divided in two parts of 24 hours each. Dr. Zaccaroni will teach “General and inorganic chemistry" and Dr. Nesci will teach “Organic chemistry”.

General and inorganic chemistry. Matter: properties, measures and classification. Structure of the atom. Periodic table and periodic properties of elements. Chemical bind. States of aggregation of matter. Chemical compounds nomenclature. Acids and bases. Chemical reactions and stoichiometry. Solutions: characteristics, expression of concentration and colligative properties, focusing on biological aspects. Chemical reactions kinetics. Chemical equilibrium. Acid-base equilibrium in water: self-dissociation of water; pH; acidic and/or basic solutions pH; hydrolysis; pH buffers; titulations; biological anphoteric electrolites. Water chemistry.

Organic chemistry. The course aims at providing information on the general properties of organic compounds and of their functional groups, by pointing out the relationship between biological relevance and chemical features. The following topics will be considered: hybridization of carbon orbitals; nomenclature and stereoisomers of alkanes, alkenes, alkynes, cyclic hydrocarbons, aromatic compounds and halogenated hydrocarbons; nomenclature and chemical properties of organic molecules featured by a functional group: hydroxyl group (alcohols and phenols); sulfydryl group (thiol); ethereal group (ethers and thioethers); amine group (amines); carbonyl group (aldehydes and ketones); carboxylic group (carboxylic acids and thioesters, amides and anhydrides); the main organic reactions (electrophilic and nucleophilic addition and substitution, elimination and condensation reactions).
