Organic chemistry

A.Y. 2019/2020
Overall hours
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 one and a half hour written test (20 questions with a closed answer) and an oral exam (30 minutes) subject to passing the preceding test. 12 correct answers out of 20 mean the candidate has passed. The correct answers are worth 1 point, wrong answers or not given are worth 0 points. The test results will be communicated via the Ariel platform. During the oral examination 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. 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.
