Learning Objectives

Basic knowledge of organic compounds, of their three-dimensional structure and of their reaction mechanisms.

In particular, the specific training objectives of this course are:

- Understanding the chemical bond in organic compounds;

- Understanding the three-dimensional structure (stereochemical) of organic compounds;

- Understanding the relationship between structure and chemical reactivity;

- Understanding the reaction mechanisms of organic compounds;

- Understanding the kinetic and thermodynamic aspects of organic compounds;

- Know the reactivity of the main classes of organic compounds.

- Discussion of all the activities proposed with scientific method and appropriate language.

Furthermore, in reference to the so-called Dublin Descriptors, this course helps to acquire the following transversal skills:

Knowledge and understanding:
- Capacity of inductive and deductive reasoning;

- Ability to rationalize the property-structure-reactivity correlations of organic compounds.

Ability to apply knowledge:

- Ability to apply the acquired knowledge to rationally describe the chemical behavior of organic compounds, including stereochemical aspects;
- Ability to predict the chemical reactivity of organic compounds based on their molecular structure.

Autonomy of judgment:
- Critical reasoning skills;

- Ability to identify the most suitable conditions for the chemical modification of an organic structure.

Communication skills:

- Ability to describe the structure and chemical behavior of organic compounds in oral form, with properties of language and terminological rigor.
