Learning objectives
Knowledge and understanding: the course will provide the students with
the theoretical and practical knowledge of the main experimental
techniques of the organic chemistry laboratory. Special emphasis will be
given to safety related issues. Moreover, the course content
complements the theoretical concepts acquired in the Organic Chemistry
I course.
Learning skills: the students will master a formally corrected scientific
language. They will also be able to clearly express organic chemistryrelated
concepts and to write a scientific report.
Applying knowledge and understanding: at the end of the course, the
students will be able to independently carry out the purification and
characterization of an organic compound working in safe conditions.

Teaching methods
The course will be held through 32 hours of lectures and 30 hours of
laboratory experiences.
Assessment methods and criteria
The practical laboratory exam will verify the ability to plan and
independently carry out simple laboratory operations involving organic
compounds working under safe conditions.
The oral exam will test the knowledge of the theory related to the
laboratory experiences, the ability to explain the IR or UV-Vis spectra of simple
organic compounds and the ability to solve simple connected exercises
