Syllabus Information

5.1. Methodological overview

The learning process for this subject has been based on:
• Theoretical classes (4 ECTS)
• Laboratory Practices (1 ECTS)

5.2. Learning tasks

The learning program offered to the student to help achieve the expected results includes the following activities:

1.- Learning activity to acquire basic knowledge of Organometallic Chemistry. This activity comprises 40 sessions (50 min/session) of lecture-interactive classes in a large group, part of the lecture will be dedicated to solving problems associated with the corresponding topics.

2.- Formative laboratory activity. It will be held in the laboratory Nº 1 on the basement of building D, in three sessions of 3.3 hours. This activity is an obligatory attendance in which the students, individually, will carry out the synthesis of a series of ligands and complexes that must characterize from the spectroscopic data that the teachers will provided.

3.- Tutorials. Teachers will reserve 6 hours a week for individual tutorials with the students.
