67062 - Organic Chemistry with Laboratory

Academic Year 2022/2023

  • Moduli: Letizia Sambri (Modulo 1) Mauro Comes Franchini (Modulo 2)
  • Teaching Mode: Traditional lectures (Modulo 1) Traditional lectures (Modulo 2)
  • Campus: Ravenna
  • Corso: First cycle degree programme (L) in Chemistry and Technologies for the Environment and Materials (cod. 8515)

Learning outcomes

When the course ends, the students develop a basic knowledge of the Organic Chemistry. The basics are: naming and structure of organic compounds; graphical drawing of the chemical structure of organic compounds, structure and reactivity of the functional groups, isomeric structures concepts, regio- and stereoisomerism, structure and reactivity of reactive intermediates. A second set of required concepts includes simple organic reactions: electrophilic and nucleophilic substitution to aliphatic and aromatic systems; addition and elimination reactions; nucleophilic addition and nucleophilic substitution to carbonyls. The students learn also the main experimental techniques employed in organic chemistry: distillation, solvent extraction, crystallization and chromatograpy, the methodologies employed in simple organic reactions and the classic characterization methods. Finally, the students grow sensitivity to the risks involved in the laboratory techniques, how to use the individual safety devices and how to manage and dispose of glass devices and chemicals.

Teaching methods

Lessons supported by electronic presentations, exercises, and practical activity in the laboratory (introduction during the lectures) performed by the students under the supervision of the teacher.

Lessons and lab practice could be modified, due to the pandemic emergency, by directives by Italian authorities.

As concerns the teaching methods of this course unit, all students must attend Module 1, 2 [https://www.unibo.it/en/services-and-opportunities/health-and-assistance/health-and-safety/online-course-on-health-and-safety-in-study-and-internship-areas] online, while Module 3 on health and safety is to be attended in class. Information about Module 3 attendance schedule is available on the website of your degree programme

Assessment methods

The assessment methods consist in a written exam (within 2 hours, without notes and books except the periodic table) and a lab test.

The written exam consists in 4 open questions, on the theoretical part of the course about the structure, synthesis, purification and reactivity of organic molecules (6 X 4= 24 points maximum).

The laboratory test consists in an experience in the lab followed by a short discussion with the teacher (12 points maximum).

The maximum score is 36 on 30, from 32 the final score will be 30 cum laude.

Enrollment in Almaesami is mandatory

Teaching tools

PowerPoint presentations (whole course) and written lectures (laboratory section only) by the teachers will be available on-line.
