Objective of the course
The aim of the present course is to introduce the student to the main experimental procedures in Organic Chemistry (extraction, crystallization, chromatographys techniques, distillation), allowing him to perform synthetic sequences, isolating and purifying the products. The student will be trainied to operate appropriately and independently in a laboratory of organic chemistry. In order to pursue this goal, the experimental work will be developed individually by any student.
Prerequisites and examination methods
Fundamentals of Organic Chemistry and basic General Chemistry laboratory techniques
Examination methods: 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. 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.
Mode of examination
Discussion of the activities carried out during the frequency in the laboratory and the proposed final evaluation .

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.
All of the experiences are "single bench".
