Learning objectives
The program's goal is to give to the student the basic instruments to
rationally
understand some of the fundamental processes of the organic and applied
chemistry.
Prerequisites
Good knowledge of the fundamental principles of the general chemistry, in particular of the atomic structure, of the chemical bond and of the chemical equilibrium; in addition the student must have a good knowledge of the acid/base concepts.
Course unit content
The students will be first introduced to the basic theories of VSEPR and of the valence bond for the description of organic molecules. Some basic concepts of chemical thermodynamics and kinetics will be also reminded with particular attention to 1st and 2nd order reactions, to chemical catalysis and to competitive reactions. The concepts of nucleophile and electrophile, those of Brønsted-Lowry and Lewis acid and base will be considered. The concepts of organic stereochemistry will be described together with the stereochemical nomenclature and properties of the stereoisomers. A systematic survey of the structure, properties and reactivity of organic molecules, divided by functional groups, will be undertaken. In particular this analysis will include the following classes of organic compounds: alkanes and cycloalkanes; alkenes, dyenes and alkynes; alkyl halides; alcohols, ethers and thiols; benzenes and aromatic compounds; amines.

Teaching methods
Oral lessons and weekly exercises. The lessons will be organized in presence with the possibility to have lessons also remotely in asynchronous mode (uploaded on the Elly page of the course)
Assessment methods and criteria
The examination will consist in a written test (2 hours) followed by and oral discussion aimed to verify the ability of the student to face organic reaction problems. The exam is passed with a score of at least 18.
