The foundations of this discipline create the basis for advanced studies in medical, biological, chemical, and materials sciences. Furthermore, using this knowledge allows us to understand some modern technologies of daily use. Through the recognition of functional groups, the three-dimensional design of molecular structures and the interpretation of the mechanical processes of reactions, the student will be able to obtain theoretical training functional to face and successfully overcome the subsequent theoretical-practical teachings, such as pharmaceutical chemistry, biochemistry, drug analysis, laboratories, etc. This training also aims to provide students with the essential elements of organic chemistry necessary for developing professional skills to engage in the work activities the future pharmacy graduate envisages AIMS AND CONTENT LEARNING OUTCOMES Fundamental knowledge of organic chemistry: recognition of classes of organic molecules, identification of functional groups and basic reactivity, understanding of the structure of the main classes of natural compounds. AIMS AND LEARNING OUTCOMES The program aims to help understand the relationships between the structure and reactivity of the main functional groups, aromatic and heteroaromatic systems. Pupils will have to understand the fundamental principles of the chirality of organic compounds and the importance of this principle in biological systems and in the synthesis of pharmacologically active chiral substances. The mechanical study of reactions for the synthesis of model molecules will allow the student to link the reactivity of functional groups to the three-dimensional structures of the resulting compounds, preventing the student from memorizing lists of disconnected reactions. The student must develop skills in designing a multistage synthesis using acquired synthetic strategies for solving problems. Understanding and reasoning are the basis for learning the subject. Mastering organic chemistry requires a deep understanding of some fundamental principles and the ability to use these principles to analyse, classify and make predictions. Students will be directed to the study of organic chemistry to obtain a series of skills and abilities useful for completing scientific training that will enable them to analyze, classify, explain, and predict the reactivity of organic compounds. Students will have to know the fundamental theories to be able, with reasoning, to solve organic chemistry problems. They will have to be able to argue theories, master graphic skills, and use technical and correct language to be able to demonstrate measurable learning results during the written and oral tests. At the end of the course, students will be able to: 1. Use the periodic table to determine the electron configuration in the ground state and the bond geometries of a central atom; 2. Interpret atomistic and molecular theories to understand the strength and nature of chemical bonds; 3. Use molecular models for the determination of molecular geometries; 4. Predict the chemical nature (electrophile, nucleophile, acid and base) of an atom within a molecular structure; 5. Master the fundamental concepts of stereochemistry with the use of 3D models, visualization software and drawing chiral molecules on paper; 6. Visualize and spatially orient the substituents in a molecule as well as being able to draw the interconversion of structural representations during a multistep reaction; 7. Classify the reactivity of organic compounds and functional groups within a molecule or between different molecules; 8. Recognize the acidic or basic nature and strength of a certain compound by attributing the position of an acid-base equilibrium; 9. Recognize the electrophilicity, nucleophilicity and propensity to leave a given atom or functional group; 10. Determine the relative stability of carbocations and radicals to understand the progress of a reaction for a specific mechanism; 11. Predict whether a reaction occurs, or not, and by what mechanism; 12. Correctly draw the curved arrows to represent the flow of electrons in an ionic reaction and in radical processes; 13. Represent the resonance limit structures of a compound; 14. Understand the connections between the organic reactions studied and those that occur in nature and in cell biology. 15. The students will be able to create multimedia products (individually or in groups) using a correct scientific language. 16.The student will be able to self-evaluate their own work and evaluate other people's work through a peer-review process. PREREQUISITES General and inorganic chemistry TEACHING METHODS The course includes 3 weekly lectures of 2 hours each, during which all the notions relating to the organic chemistry teaching program are transmitted to the students. Teaching materials to support the lessons (presentations, exercises, and in-depth articles) are provided to students through the aulaweb platform. Fundamental texts are recommended for the study of theory and for carrying out the exercises. However, part of the lesson is carried out on the blackboard, using digital media and molecular models to educate the student in the two- and three-dimensional design of molecules and in the carrying out of chemical reactions with the relative mechanism. To face dynamic frontal lessons, the active participation of students is required in answering questions and carrying out exercises individually or in groups. Quizzes and exercises will be available on the aulaweb platform to keep the study updated, which allows a profitable accompaniment of the lessons throughout the teaching period of organic chemistry. Activities are planned to promote the ability to peer-review and self-evaluate the papers to promote the ability to learn to learn (basic level). The production of multimedia products is encouraged to develop functional alphabetic skills that allow the student to seek and process information, present, communicate and argue theories and practical concepts in both oral and written form (basic level). Tips on how to study: 1) keep the study of the weekly topics updated, never let them accumulate; 2) study the material in small teaching units and make sure you understand each new section before moving on to the next; 3) solve all the problems of the chapter; 4) write during the study in a theory and exercise notebook; 5) learn by teaching and explaining (study better in a group); 6) use molecular models during the study. Any Student with documented Specific Learning Disorders (SLD), or with any special needs, shall reach out to the Lecturer(s) and to the dedicated SLD Representative in the Department ( Prof. Luca Raiteri, Luca.Raiteri@unige.it ) before class begins, in order to liaise and arrange the specific learning methods and ensure proper achievement of the learning aims and outcomes.
