Course objectives
This course is a follow up of the course of Structure and Reactivity. The aim of this course is for students to gain knowledge of elemental steps of chemical transformations and reactive intermediates and to help them to use the scientific literature in the corresponding field and interpret the results from the experimental and theoretical studies.
Learning outcomes
In the end of this course, the student will be able to understand the details of the mechanisms of chemical transformations, which are studied using chemical and physical tools.
