Organic Chemistry
A.Y. 2023/2024
Learning objectives
Organic substances such as fundamental building blocks of living material. We will describe the structure, the physical-chemical properties and reactivity of the major classes of organic compounds, with particular emphasis on those most important in food matrices.
Expected learning outcomes
1. Knowledge of basic classification and nomenclature of organic compounds, as fundamental building blocks of living material. 2. Understanding of the relationships that exist between the chemical formula, three-dimensional structure and physical-chemical properties (solubility, volatility, color, etc..) of organic molecules. 3. Knowledge of the main reactions of organic compounds: acid-base reactions, oxidation-reduction, hydrolysis, etc. radical reactions.

Assessment methods and Criteria
The exam consists of a two hours written test and of a short oral exam concerning questions relating to the laboratory. The test consists of 6 questions (open theory questions, exercises to be carried out). The test results will be communicated via the SIFA platform. The correctness of the candidate's language and of the chemical terms will be evaluated. Furthermore, the ability to link the various topics covered in the course will be evaluated. The vote will be out of 30. The test includes all the topics of the course plus those covered in the laboratory. The laboratory is strongly suggested. Students with DSA certification are required to promptly notify the Teacher to agree with the methods of examination. Students enrolled in an exam session and no longer wishing to support it are required to unsubscribe. It is mandatory to have taken the General and Inorganic Chemistry exam.
