Learning outcomes

After successful completion of the course, students are able to carry out one- and two-step synthetic procedures from the fields of organic and inorganic chemistry using common synthetic methods. They can separate mixtures of substances and are able to identify the resulting pure compounds. In addition, students are able to manage their time autonomously, especially when several tasks have to be performed at the same time, and they know how to interact professionally with colleagues and teaching staff.

Subject of course

Synthesis of organic and inorganic compounds according to different mechanisms and using different working techniques as well as characterization of the compounds by different methods. The compounds are organized in thematic complexes, whereby the student is assigned individual examples from a group of methodologically similar syntheses. The program includes the syntheses of organic compounds by nucleophilic or radical substitution, addition or elimination, reduction or oxidation, aromatic substitution, condensation, diazotization and a transformation of/to a carbonyl or carboxyl derivative. A compound thereof is to be prepared on a semi-microscale. Furthermore, a mixture of substances is to be separated and the pure substances contained therein identified, a natural substance is to be isolated and a reaction with an organometallic reagent is to be carried out. In the field of inorganic synthesis selected substance classes of inorganic and metal-organic chemistry are synthesized: simple metal complexes, molecular inorganic compounds of the main group elements, the use of Li- or Mg-organyls in inorganic chemistry and metal-organic compounds of transition metals (metal carbonyls, sandwich complexes etc.). All products are characterized by suitable spectroscopic and/or chromatographic methods. Important points are also environmental awareness and disposal of by-products. Before each product is prepared, a discussion must be held. ECTS credits are assigned to the individual subject areas as follows: Inorganic chemistry 5.5 credits, organic chemistry 9.5 credits.

Teaching methods

The necessary practical work must be carried out and prepared autonomously. In particular, it is required to acquire the theoretical background knowledge independently, to plan and conduct the experiments, to analyze the final products and to interpret the analytical data obtained. All work steps must be documented accordingly in a protocol.

Examination modalities

A three-component mixture must be separated and the pure substances contained must be identified. 13 syntheses must be performed and the products obtained must be characterized. The theoretical basics and practical execution of the individual preparations are checked in a preliminary interview before the start of the experimental work to ensure that the students are able to carry out the experiment successfully and are aware of the safety aspects. A protocol about the execution of the experiment and the evaluation of the analytical data has to be written. When the preparation is delivered, the laboratory journal, protocol, yield and purity of the products are checked and evaluated. After completion of all experimental work, follows a debriefing in which the students are asked again about the experiments and analytical evaluations they performed during the laboratory exercise. The grade of the laboratory exercise is calculated from the mean value of the individual grades of the experiments, whereby these are derived from the partial grades for the preliminary discussion, performance of the experiment (yield and purity of the products) and protocol with a weighting of 20:60:20.

For a positive overall assessment, all partial performances must be positive, whereby negative partial performances can be corrected by repetition. The number of negative preliminary discussions must not be greater than 4.
