LEARNING OUTCOMES

Acquire the fundamental concepts that allow to understand the structure and reactivity of the main classes of organic compounds, with particular emphasis on the biologically important reactions. Acquire a basic knowledge of the main primary metabolites. To be able to execute some of the typical practical procedures of an organic chemistry laboratory. To be able to work in group and to write a laboratory report.

TEACHING METHODS

Traditional lessons in the classroom (54 hours). The solutions of problems will be treated in additional and optional tutoring hours (10). Laboratory sessions (7 sessions of 4 hours each).

The attendance is compulsory. Students must attend all laboratory sessions and 60% of the classroom lessons.
