The aim of the course is to provide students with the basic knowledge of organic chemistry. Basic reactivity of
selected organic compounds (including carbonyl compounds such as aldehydes ketones, carboxylic acid and
derivatives, amines, aminoacids, and sugars), will be discussed as well as pericyclic reactions.

Požadavky ke zkoušce

Poslední úprava: PharmDr. Eliška Matoušová, Ph.D. (17.02.2022)

The credits from the tutorial course are needed for enrolling for the exam.

The exam will be in the written form, covering the material discussed during the lectures and included in the recommended literature.

The conditions for successful fulfilling of the tutorial lectures are as follows:

• 70% attendance (in case of absence higher then 30%, it is necessary to rationalize the absence by a medical or other document)

• Working out four homeworks.

• Passing a final test with at least 60%.
