Learning Objectives
The objectives of the course are to provide students with a good understanding of the theoretical and applicative aspects of organic chemistry. The primary objective of the course is to transmit students the language of organic chemistry, with particular reference to nomenclature, physical-chemical properties of the organic compounds and the structural characteristics of the functional groups. A particular focus will be on the structure, properties and reactivity of biomolecules, carbohydrates, amino acids, proteins and lipids.

Learning Achievements (Dublin Descriptors)
Knowledge and understanding skills. The student will need to know the principles underlying the chemical bond, the nomenclature rules of organic compounds, be able to highlight the relationship between formulas, spatial structures and molecular properties.
The student will have to know the basic concepts of acidity and basicity according to Lewis rules, the stereochemistry, knowing and distinguishing enantiomers and the differences with the diastereo-isomers; the student will also have to master the Fisher Formulas.
The student must be able to identify the various functional groups, distinguishing between an aliphatic and an aromatic compound, the interactions between functional groups, their preparation and reactivity. The student will have to know the main biomolecules and relationships that bind the various functional groups that compose them and reactivity.
These skills will be verified through a written test and oral questions.
Ability to apply knowledge and understanding. The student should be able to use the various methods to describe an organic compound, nomenclature, symbols to express reaction mechanisms, resonance formulas and distinguish their energy weight. It will also apply the knowledge acquired to interpret basic acid / base properties of organic compounds.
The student will be able to synthesise and recognize organic compounds by applying the major stru-ctural and reactionary properties and the most important synthesis methods.
These skills will be evaluated through a written test.
Judgment autonomy. The student should be able to critically evaluate the structure and properties of an organic compound, both in terms of molecular complexity, stereochemistry, acid / base and reaction properties.
The knowledge acquired in the study of the different functional groups will find their full applica-tion in the student's ability to evaluate in their complexity biomolecular systems of interest for the purposes of the Study Course.
These skills will be verified both with the written test and with targeted oral application questions.
Communicative Skills. The student should be able to describe the structural and reactive concepts learned during the course by expressing it clearly, with appropriate terms and examples.
Learning ability. The student will have to be able to construct his or her scientific growth path in a critical and autonomous way, using the teaching material provided by the teacher in the form of texts and slides, as well as the in-depth material that he or she will be able to obtain. These skills, as far as possible, will be stimulated by the teacher by offering insights and providing exercises to be solved, which will then be explained and discussed during the lessons.
Teaching Material
The teaching material prepared by the lecturer in addition to recommended textbooks (such as for instance slides, lecture notes, exercises, bibliography) and communications from the lecturer specific to the course can be found inside the Moodle platform › blended.uniurb.it
Teaching, Attendance, Course Books and Assessment
- Course books
- AA.VV. "Essential Organic Chemistry" by B. Botta Edi Ermes 2012
- W. H. Brown, T. Poon "Introduction to Organic Chemistry", Fourth Edition, Edises, 2011
The proposed texts are alternative to each other
- Copy of the slides of the lessons available on the Moodle platform ›blended.uniurb.it
- Assessment
Verification of learning aims to ascertain the acquisition of the knowledge and skills expected and takes place through the final exam which consists of a written test and an oral test.
The written test consists in solving six exercises ranging from the nomenclature of organic compounds to the chemistry of biomolecules. The exercises will be written according to typologies similar to the exercises carried out in the classroom by the teacher. The evaluation of the written test is expressed out of thirty and will be considered passed with a minimum score of 18/30.
The duration of the written test is 1.5 hours. The oral test is reserved for students who have passed the written test and obtained a grade above 18/30 and will focus on questions covered by the course program.
The final evaluation will reflects the overall evaluation of the candidate.
- Disability and Specific Learning Disorders (SLD)
Students who have registered their disability certification or SLD certification with the Inclusion and Right to Study Office can request to use conceptual maps (for keywords) during exams.
To this end, it is necessary to send the maps, two weeks before the exam date, to the course instructor, who will verify their compliance with the university guidelines and may request modifications.
