Teaching methods

The teaching is delivered through lectures, which are carried out at the blackboard and with the aid of audiovisual media (Power Point presentations), classroom exercises on the spectroscopy part and laboratory practice, carried out in the lab, working in small groups. For the theory part, the teaching material consists of one of the recommended organic chemistry texts and it is strongly recommended that students take notes. Attendance to face-to-face lectures, classroom exercises and laboratory practices, although strongly recommended, is not compulsory. The frequency to less than 75% of the laboratory practice sessions, if not adequately justified, will result in the evaluation of 0/30 for each laboratory session skipped beyond the first two. Attendance at practical laboratory exercises is verified by direct appeal by those present. The course is delivered in Italian Lessons in streaming and video-recorded, if required by the pandemic

Assessment methods

The exams will take place at the end of the course, according to the official exam calendar published on the ESSE3 platform. The student can always register via the ESSE3 platform. The exam (both the written and the oral parts) can be taken only after having passed that of Organic Chemistry 1.To enroll in the oral exam, you must have passed the written exam. The three modules are evaluated in thirtieths with weight proportional to CFUs of each module. -evaluation in at the end of the course of the laboratory activities, this is based on the results of mandatory tests administered individually before each experience (80% of the assessment), on the laboratory notebook (report of the experiences and elaboration of the experimental data obtained, including spectroscopic data) (15%) and of the student behavior during practice (warning received for not using IPD or other misbehavior) (5%). The frequency to less than 75% of the laboratory practice sessions, if not adequately justified, will result in the evaluation of 0/30 for each laboratory session skipped beyond the first two. Attendance at practical laboratory exercises is verified by direct appeal by those present. -assessment of the spectroscopy module: it is based on a written examination during which the student identifies a simple organic molecule starting from the raw formula, IR and 1D 1H NMR spectra (80%), and shows to have a basic theoretical knowledge of the key topics (basic factors determining the position of IR and 1H NMR signals and the 1H NMR signal shape) (20%). - Oral examination: three questions, maximum one hour, during which the understanding of the topics covered in the class, the ability to predict the outcome of a reaction starting from given reagents or the reagents needed to prepare a product (90%) and the use of a correct language and graphic symbolism (10%) will be evaluated. KNOWLEDGE, UNDERSTANDING and ABILITY TO APPLY KNOWLEDGE AND UNDERSTANDING are evaluated in all three modules. JUDGING AUTONOMY and COMMUNICATION SKILLS and are evaluated during written and oral examinations. ABILITY TO LEARN is assessed by the degree of self-depth reached by the student in the discussion of the topics of oral and written exams. Laude is given to students who achieve a final evaluation of 30/30 and pass brilliantly the oral examination (without any help from the teacher).

Learning outcomes

Knowledge and understanding: Through lectures and exercises done with the teacher, the students learn the basics of organic chemistry related to the synthesis and reactivity of the systems covered in the course, the basis for performing safely simple organic synthesis in the laboratory and to test the structure and purity of prodoti obtained.
Applying knowledge and understanding: Through lectures, practical laboratory and exercises done in autonomy, the students are able to apply their knowledge to solve problems related to the synthesis and reactivity of organic molecules, to identify simple organic molecules and to conduct safely laboratory activities under teacher supervision.
Making judgments: through lectures, exercises and drills conducted in a controlled manner, students acquire the ability to critically interpret data on molecular properties and connected with the reactivity of functional groups.
Communication skills: the frequency to the lessons and students involvement during these allow them to develop the ability to use the specific language of the subject, to present the data obtained in a concise way, to express the concepts learned with a proper language and symbology.
Learning skills: the activities described allow the student to acquire the methodological tools for
continue their studies and to face more specialized courses.
