Objectives

The Organic Chemistry course aims to provide the student with a solid basic knowledge of the structure and reactivity of organic compounds. The ability to deal with problems connected with the design and synthesis of organic compounds is stimulated and developed in the student. Links with biochemistry and pharmaceutical chemistry are emphasized with particular attention

Contents

The main purpose of the course is to provide the student with a solid basic knowledge of the structure and reactivity of the classes of organic compounds: from hydrocarbons to nucleic acids. At the end of the course the student knows how to correctly name and represent the structure of organic compounds, recognizes the functional groups and is clear about the concepts of structural isomerism, regio- and stereoisomerism. the fundamental reactions of organic compounds and their mechanism. The frontier topics with biochemistry, pharmaceutical chemistry and environmental chemistry are highlighted and treated with particular attention

Teaching Methods

The course consists of 48 hours of frontal teaching. Each theoretical topic will be enriched with exercises in the classroom dedicated to the carrying out of exercises that will follow the topics of the lessons. The exercises will in part be carried out on the blackboard by the teacher, in part they will require the active participation of the students

Evaluation methods

Verification of learning:

The exam consists of a written test lasting 120 minutes. The written test included 6 open-ended questions with theoretical questions and exercises covering the entire program. The value of the exercises varies between 5 and 8 depending on the difficulty. The maximum achievable score is 33. If the score is 32 or higher, honors will be awarded. The teacher or student may also request an oral test which constitutes an additional element of assessment. In this case, the final mark will be established taking into account both the score obtained in the written test and in the oral test. It is important to underline that the oral test should not be understood as aimed at raising the mark obtained in the writings but, if it fails, the mark may be lowered even to the extent of rejection.
During the examination it is not allowed to consult books, notes or electronic devices of any kind
