Objectives

SPECIFIC OBJECTIVES OF LABORATORY SESSIONS
1 Performing some basic techniques (purification / identification) common in Organic Chemistry; 2 Synthesis of organic compounds; 3 Development of a critical analysis of the results; 4 Development of some autonomy in the laboratory.

Learning outcomes and competences

SKILLS THAT STUDENTS SHOULD DEVELOP:
1 Planning and structuring the practical work to be undertaken; 2. Personal autonomy in the laboratory; 3 Capacity for searching bibliography.

Working method

Presencial

Pre-requirements (prior knowledge) and co-requirements (common knowledge)

Students should have attended the following courses:
- Laboratório de Química I
- Laboratório de Química II
- Química Orgânica I

Program

There will be a total of 12sessions. 1 theoretical-pratical lesson (2,5 h), 9 lessons devoted to practical experiments, and 2 classes for practical evaluations. The lab experiments to be performed are:1- Solubility tests (4 h); 2-Identification of analgesics by TLC (2 h); 3 - Separation of the components of a mixture by liquid-liquid extraction (4 h); 4 -  Synthesis of tert-butil chloride by an SN1 reaction (4 h); 5 -  Aldol condensation: Synthesis of dibenzylideneacetone (4 h).
Last lessons: Practical Evaluation (2 h + 2 h)

Teaching methods and learning activities

The curricular unit "Laboratory of Organic Chemistry" aims at the execution of laboratory experiments in the scientific field of organic chemistry, based on the themes versed during the courses of Organic Chemistry I and II. Therefore, practical work covering several topics such as esterification reactions, nucleophilic substitution reactions,  purification processes of organic substances based on their chemical characteristics (solubility, acidity / alkalinity, density, etc.) will be carried out. Strategies used for the success in the development and planning of practical protocols in organic chemistry will be discussed, using the lab experiments to be performed as examples.

Eligibility for exams

The number of absences allowed is 3 (2 h periods). The minimum number of prectical experiments to be carried out by the student is 4 (from 5). The mark for each lab experiment which is not performed is 0 points.

Calculation formula of final grade

Terms of frequency: the maximum number of absences allowed is 3 x 2 h periods. The minimum number of complete practical experiments carried out by the student is 4. The practical grade (PG) has to be equal or higher than 9.5.
The PG is calculated by the following formula:

PG = 0,55 x IP + 0,15 x QE + 0,30 x APF

where IP is the practical assessment made by the teaching staff, QE is the mark obtained in the written questionnaires given throughout the practical sessions and APF is the mark obtained in the final practical evaluation.

Special assessment (TE, DA, ...)

The student must perform a lab experiment and the corresponding report to be defined by the teacher. The mark has to be equal to or higher than 9,5.
