Teaching language

Suitable for English-speaking students

Objectives

To know the different families of organic molecules in terms of their reactivity, the reaction mechanisms in which they are involved and their synthesis. To understand the relationship between structure and function of organic molecules. Demonstrate, through examples from everyday life, the role of organic chemistry in the development of some areas of modern biology, medicine and the synthesis of new products and materials. Apply the chemical concepts learnt to concrete situations in life sciences and industry.

Learning outcomes and competences

Students should acquire the ability to recognise the main reactions of a variety of functional groups, the mechanisms involved and the structure-reactivity relationships of the main families of organic compounds (aldehydes and ketones, carboxylic acids and their derivatives, benzene and its derivatives), with particular emphasis on biomolecules (carbohydrates, lipids, proteins and nucleic acids). Through the laboratory work carried out, students should become familiar with and be able to apply the basic techniques of isolation, purification and identification of compounds related to organic synthesis.

Teaching methods and learning activities

In lecture classes (2h per week; distance learning classes via zoom) the syllabus will be presented using multimedia: presentations using datashow and active learning platforms. The classes will be available in the discipline webpage (Moodle).

In practical classes (2h per week, classes of compulsory attendance), the students, in groups of 2 elements, properly protected with glasses, gloves and labcoat, will perform laboratory works, in the Organic Chemistry scientific area, which include some basic purification and identification techniques common in this scientific area as well as the synthesis of organic compounds.

Eligibility for exams

Practical classes are compulsory for all students (with the exception of students who passed the practical part in the previous five academic years).            

 

Maximum number of absences according to the statutes.

 

In order to obtain a pass mark, students must obtain a grade of at least 9.5 both in the practical laboratory work and in the average of the two tests or in the final examination.

The first test is held in the middle of the semester and the second on the day of the regular exam.

Calculation formula of final grade

The final grade of the curricular unit (NF) is made up of five parts with different weights, the average classification of the 20 best answers to the questions asked in the lectures (QA), the practical classification (CP), the classification of test 1 (CT1), the classification of test 2 (CT2) and the classification of the final exam (CEF), according to the algorithm:

CF = 0,10 x QA + 0,30 x CP + 0,15 x CT1 + 0,15 x CT2 + 0,30 x CEF

 

 

The practical information (CP) includes: - Preparation and execution of the practical work (70%; 30% flowchart + 40% laboratory performance)) - Recording on the report sheet (30%)

To pass the course, students must achieve a final mark of no less than 9.5, and the practical mark must also be no less than 9.5.

Students who do not pass the course in the normal period may be assessed on the theoretical component by a comprehensive exam in the appeal period, although this assessment will only contribute 70% to the final grade. The remaining 30% of the final grade will come from the practical grade.

Special assessment (TE, DA, ...)

Students who are unable to attend practical classes may apply to take a practical examination during the normal examination period, the result of which will replace the practical classification.

Classification improvement

 The final mark for the theory part (70%) obtained in the normal exam period can be improved in the appeal exam period.

 

Observations

Students who have an excused absence from one of the tests will be able to retake it on the day scheduled for the final exam of the normal term.
