Course objectives
The main aim of the practical course is to teach fundamental laboratory methods of organic chemistry in synthesis (heating, stirring, cooling, introduction of gases, working at lower pressure, drying) and separation of organic compounds (filtering, crystallization, distillation, extraction). These methods are exercised on important types of organic compounds syntheses. The products are characterized by melting point, thin-layer chromathography, refractive index, and IR-spectroscopy.

Teaching methods
laboratory exercises
Assessment methods
Every exercise is started by testing knowledge and preparation for the certain synthetic method by computer. After passing the practical exercise in the laboratory a protocol of the synthesis has to be submitted.
Language of instruction
Czech
