Organic Chemistry 1
A.Y. 2020/2021
Learning objectives
The objectives of the Organic Chemistry 1 course are aimed at the learning, by the student, of the fundamental principles of organic chemistry: from the nature of chemical bonds to the molecular structure, from the shape of the molecules to the stereochemistry up to the study of the reactivity of the organic compounds based on the nature of their functional groups. Therefore, the ability to recognize functional groups, the understanding of reaction mechanisms and the critical evaluation of related stereochemical aspects are the fundamental objectives of teaching. The purpose of this course is to provide a reasoning method to facilitate the learning of the basic notions. In this regard there will be numerous examples of practical application of the concepts taught and the lessons will be accompanied by exercises on the blackboard with the aim of deepening and assimilating the topics covered in the theoretical lessons.
Expected learning outcomes
At the end of the course, students must be able to: - acquire the appropriate terminology to name the molecules and describe their reactivity; discuss the mechanisms of organic reactions applied to specific substrates; propose synthetic routes for the construction of simple organic molecules; - possess the ability to present their knowledge in a clear and orderly manner, with appropriate scientific language and with rigorous arguments.

Course syllabus and organization
Single session
Lesson period
year
The hours that will be held in the first semester will be held on the teams platform in synchronous mode. Face-to-face meetings are scheduled at the end of the first semester (January) mainly dedicated to exercises. In the second semester it is hoped to be able to carry out the course face to face. If this is not possible, we will continue in sinchronous mode (TEAMS) with at least 6 hours of face to face practical training

Assessment methods and Criteria
The examination consists of a written and an oral test.
- Written exam: 10 exercises to be carried out in two hours. Each exercise requires the acquisition of a score between zero and three points. The passing of the written test, and therefore the admission to the oral test, is achieved upon reaching a total of 18 points.
- Oral test: it takes place after the time necessary for the correction of the written test, (approximately after one week) and concerns the theoretical topics covered by the course The final grade is formulated by the teacher evaluating the overall preparation and the competences acquired
