1. Aim of the subject:
The aim of organic chemistry is to provide fundamental knowledge on the structure, synthesis of organic derivatives with different functional groups, on their reactivity with an insight into the mechanism or stereochemical aspects. During their studies of organic chemistry they will face a number of new notions, definitions, chemical structures, structural features and a number of new aspects of the chemical transformations.
The aim of the practice is the formation and development of the student’s laboratory skill. According to these skills the students will be able to acquire the most important laboratory operations (distillation, crystallization, filtration, melting point definition, extraction, evaporation, etc).

2. Requirements:
Semaphors (subjects): qualitative analytical chemistry
