10. Experimental Organic Chemistry

Study-Unit Aims:

This study-unit aims to present the reactions of the most common classes of simple organic compounds as detailed in the study-unit description. Furthermore, students will also be trained to perform organic chemistry experiments and interpret results.

Learning Outcomes:

1. Knowledge & Understanding:

By the end of the study-unit the student will be able to:
- Classify organic compounds in relation to the functional groups present in the molecule and assign the appropriate name to the organic molecules according to IUPAC rules.
- Illustrate the reactivity and the main reaction mechanisms of the common organic functional groups as mentioned in the study-unit description.
- Propose synthetic routes to simple chemical structures.

2. Skills:

By the end of the study-unit the student will be able to:
- Manage information to solve problems.
- Perform organic chemistry experiments safely.
- Check the correctness and reliability of method.
- Interpret correctly and verify the results of organic experiments.
- Discuss results of experimental work in relation to established knowledge.
