Learning objectives

To acquire knowledge and ability to understand matters of Organic Chemistry in advanced books. Ability to apply knowledge of Organic Chemistry with a professional approach, to design, to discuss and solve problems in the field of Organic Chemistry; to acquire maturity and the necessary skills to undertake studies of higher grade with a good degree of autonomy.
Knowledge of the structure and reactivity of organic molecules, with
particular attention to the biological substances. To acquire knowledge on
classification and nomenclature of the organic compounds by the identification of
their functional groups and , through these, on their reactivity. To learn the concepts
of isomerism, conformation and stereochemistry of organic molecules and of their
consequences in biological systems. To learn the principal concepts characterizing the reactivity of organic compounds in radicalic, electophilic and nucleophilic
reactions. To know the functional groups and properties of some important classes
of biological compounds, such as carbohydrates, triglycerides and amino acids.
To describe the biopolymers of fundamental importance in biological systems:
polisaccharides, peptides, nucleic acids, and their chemical features, their biological role and fundamentals about chemical synthesis of these molecules.
To acquire experience on the principal laboratory techniques for the purification and modification of organic compounds.


Knowledge of the concepts of General and Inorganic Chemistry

Teaching methods

Lectures, tutorials and laboratory practice. During the lectures the principles of organic chemistry nomenclature, physical and chemical properties and reactivity of the major classes of organic molecules and biological macromolecules will be addressed. In the tutorials exercises concerning the structure and reactivity of organic molecules and the related problems of understanding will be presented in an interactive manner and discussed with the students. The part of the practical training is preceded by an explanation in the classroom of the risks and protective measures to be used in the laboratory and by the detailed explanation of the procedures of each experience. The experiences consist of laboratory work in small groups (2-3 people) under the supervision of the teacher and experienced staff, followed by a re-elaboration by the student in a written report.

Assessment methods and criteria

The exam consists of a written test and an oral test upon delivery of lab reports
The knowledge required to pass the exam are:
Demonstration of knowledge and understanding whilst supported by advanced textbooks of Organic Chemistry. Ability to apply knowledge of organic chemistry with a professional approach to design, sustain arguments and solve problems in the field of Organic Chemistry; acquire the maturity and knowledge necessary to undertake further studies with a high degree of autonomy
Demonstration of knowledge of the structure and reactivity of organic molecules, in particular of biological compounds. Knowledge in the classification and nomenclature of organic compounds through the identification of functional groups that characterize them and, through them, in the description of reactivity. Knowledge of the concepts of isomerism, conformation and stereochemistry of organic molecules and the consequences of these in biological systems. Knowledge about the major concepts that govern the reactivity of organic compounds in reactions of radical type, electrophilic or nucleophilic. Knowledge of the functional groups and the properties of some important classes of biological molecules such as carbohydrates, triglycerides and amino acids. The student should demonstrate that he understands and can re-elaborate the main laboratory techniques for purification and modification of organic compounds used during the practical sessions.
The written exam consists of 6 exercises of reactivity of organic compounds solve. It is passed with 4/6 questions are carried out correctly or, alternatively, if at least 60% of the total content expressed are correct and comprehensive.
The oral examination consists of the discussion of the laboratory notebook and a deepening of the theoretical part, in particular of parts not included in the written exam.
