Chemistry
(objectives)
The course introduces the concepts and the experimental approaches of organic chemistry, working on the consolidation of principles acquired in the field of physics and general and inorganic chemistry to advance the knowledge of carbon chemistry. In the first part of the course, the cultural and practical bases for understanding the structure of organic molecules will be provided, paying particular attention to the existing relationships between the chemical structure and the chemical-physical and biological properties associated with them. The different physical hybridization states of the carbon will allow the three-dimensional vision of the molecules, facilitating the understanding of their role in the cell. The second part of the course is dedicated to the application of properties in the context of chemical reactivity. The student will have the opportunity to have answers to some of the key questions in his study: why do molecules react? What are the experimental factors that control the kinetics of the reactions? When is a reaction under thermodynamic control rather than kinetic? How is it possible to synthesize complex molecules from simple reagents? What is the impact of organic chemistry on the environment and how can it be reduced? This knowledge will allow the student to undertake subsequent study courses with strong structural and molecular expertise.
B) EXPECTED LEARNING RESULTS Knowledge of the principles governing the formation of the chemical bond, using traditional theories (valence bond theory) and advanced theories (theory of molecular orbital and quantum mechanics ). Knowledge of nomenclature and classification (theory of functional groups) of organic molecules, with particular attention to the association between the family of organic molecules and biological and chemical-physical properties. Knowledge of the reactivity of organic molecules and experimental parameters capable of controlling thermodynamics and kinetics of organic transformations. Knowledge of the relationship between organic molecules and the origin of life.
In addition to the knowledge gained through the study of organic chemistry, students will be able to apply the acquired concepts for the resolution of practical exercises related to the identification and classification of substances based on Their activity on the body, the effect of chirality on pharmacological activity, the possibility of separating organic isomers and the general methodologies for their analysis and their recognition.
Making judgments: The course offers links to other disciplines (Physics, General Chemistry, Biochemistry, Molecular Biology, Computational Chemistry and Genetics) by providing an integrated knowledge. The student's critical judgment will be stimulated by constantly referring to the reading of recent studies published in scientific journals, questioning the current issues related to some of the core concepts of the discipline. Thanks to the multi-disciplinary and interdisciplinary nature of organic chemistry, it will be also possible to link the acquired concepts to other disciplines, allowing the student to form his own autonomy of judgment about the effectiveness of an integrated scientific approach.
Communication skills: At the end of each part of the course, the students will be invited to form working groups to develop solutions and compete with others in solving practical exercises. The educational gain is aimed at increasing the communication skills and the ability to know how to work in a group, all aimed at consolidating the acquired concepts.
Learning Skills: Students' learning abilities will be evaluated during the course of the course by exonerary tests that will allow you to individually monitor the maturation state of the knowledge, highlighting the student's ability to return.

Module:
Inorganic chemistry
(objectives)
1) Knowledge and understanding: at the end of the course which also includes the organic chemistry module, and following the individual study commitment, the student has an adequate knowledge of the chemical concepts preparatory to the correct understanding of the subsequent TAE programs that involve basic and more advanced concepts of general and inorganic chemistry.
2) Ability to apply knowledge and understanding: At the end of the course and following the individual study commitment, the student achieves an adequate preparation which, together with other, more specific knowledge that he/she will acquire later on, will allow them to move and operate in areas of innovative applications, including international ones. The student will be able to use the fundamentals of chemistry for specific applications in the agri-food and oenological fields, also for the development of eco-sustainable methods and productions. By way of example, the student will be able to orient himself in the choice of different products, making this choice also on the basis of the knowledge acquired.
3) Independent judgment: At the end of the course and following the individual study commitment, the student is able to critically interpret any data relating to production processes in the food and wine sector. The student is able to evaluate possible qualitative aspects related to the use of preservatives and additives. The autonomy of judgment will be mainly oriented towards an assessment of the quality of the food product.
4) Communication skills: At the end of the course and following the commitment of individual study, the student is able to communicate and share knowledge related to the discipline to interlocutors of the same level and non-specialists. The student is able to interact constructively, in relation to the studied discipline, with other people of similar cultural background. These skills are also developed thanks to individual commitment, written tests and oral tests, which represent the moment of synthesis of the study path.
5) Learning skills: At the end of the course and following the individual study commitment, the graduate student has developed a certain degree of critical approach. And he/she now knows how to find all the useful information to contextualize a problem, through the use of the tools offered by scientific literature.
