Classroom exercises (pre-laboratory): 16h
1- Safety and accident prevention in the chemical laboratory.
2- Main techniques of isolation and purification of organic compounds (extraction, crystallisation, simple distillation, fractional distillation, chromatography),
3- Introduction to IR spectroscopy.
4- Experimental aspects of some fundamental organic reactions and evaluation of the purity grade of the obtained products through TLC and mp.
Laboratory Chemical Manipulations: 64 hrs
Practical execution of separation and purification procedures of organic compounds (extracions, cryistallization, chromatography, distillation) and of simple organic reactions referring to the reactivity of functional groups. In particular, oxidations of alcohols, reduction of carbonyls, esterifications and aldol condensations will be performed. The students will learn also to prepare samples for IR spectroscopy and to register IR. At the end of the laboratory, students will have to demonstrate at least a basic familiarity with the practical operations of experimental organic chemistry, and capability to correctly evaluate the purity of isolated products.
Suggested prerequisites [required]
To have attended the General Chemsitry and Organic Chemistry I course; to have attended or attend the Organic Chemistry II course. Il is mandatory to have attended the first module of the Organic Chemistry Laboratory to be admitted to the second module.

Knowledge of the basic principles of Organic Chemistry.
practical and oral
The examination will consist in the communication of the score (maximum 30/30), which represent the average of the evaluations of the two session of practical experiences (based on the practical results obtained in the lab as well as on the required reports). The student will then have the possibility to sustain an oral examination in order to improve the score. The oral examination will be focused on all the arguments treated during the course. The oral examination not necessarily implies an improvement of the rating.
