Prerequisites
Although there are no official pre-requisites, it is very convenient for the student to review:
- The concepts of stoichiometry learned in high school.
- The Lewis model for the representation of chemical structures.
- The basic knowledge of nomenclature of organic chemistry, as well as the representation of chemical bonds seen in the baccalaureate.
Objectives and Contextualisation
It is a first-year subject, of basic training in the foundations of organic chemistry, both from the structural point of view and chemical reactivity. The acquired knowledge should allow students who pass the subject to understand the concepts of isomerism related to organic compounds, as well as to interpret chemically most of the biochemical processes that will later be seen in other subjects of the degree.
More specifically, the objectives of the subject are:
1) Achieve knowledge and understanding of the basic concepts of the various binding theories applicable to organic compounds.
2) Be able to describe and understand the different types of isomerism of organic compounds.
3) To identify and describe the reactivity and reaction mechanisms of the main organic reactions, as well as the various factors that affect them.
Competences
- Analyse, summarise, resolve problems and make professional decisions.
- Apply knowledge of the basic sciences to food science and technology.
- Apply the scientific method to resolving problems.
- Display knowledge of the physical, chemical, biochemical and biological properties of raw materials and foods.
Learning Outcomes
- Analyse, summarise, resolve problems and make professional decisions.
- Apply the scientific method to resolving problems.
- Describe the different types of isomerism in organic compounds.
- Describe the mechanisms of the principal organic reactions and the various factors that affect them.
- Describe the structure of the atom.
- Describe the technofunctionality of organic compounds in accordance with the characteristics of the environment.
- Distinguish between the different types of chemical bonds and intermolecular interactions.
- Identify the basic reactivity associated with the various functional organic groups.
- Identify the functional groups of the principal natural organic products and their most important reactions.
- Name and formulate the organic and inorganic chemical compounds.

* Unless the requirements enforced by the health authorities demand a prioritization or reduction of these contents
Methodology
The development of the course, in terms of teaching methodology* and training activities, is based on the following activities:
- Lectures, where the student acquires the theoretical knowledge of the subject on the one hand and on the other hand, attends and participates in the resolution of related problems. These classes will be developed asynchronously with engraved material.
- Seminars, which are sessions with a small number of students that should serve both to answer questions and to delve into certain key concepts and their application in practical cases.
- Evidences, which are evaluable exercises of individual realization on the part of the students. These can be commissioned as work outside the classroom or as a substitute for a master class at the decision of the responsible teacher.
* The proposed teaching methodology may experience some modifications depending on the restrictions to face-to-face activities enforced by health authorities
Annotation: Within the schedule set by the centre or degree programme, 15 minutes of one class will be reserved for students to evaluate their lecturers and their courses or modules through questionnaires.

Assessment
The evaluation of the scientific-technical knowledge of the subject achieved by the student, is done individually, continuously and through written tests consisting of: *
- 2 partial exams with an incidence in the final mark of 40% the first and of 50% the second. The minimum grade required to pass the course is 5.0 in each part.
- Resolution of evidence with an incidence of 10%. Evidence is required, so students who fail to do so will automatically be graded with a zero.
- For students who have not passed one of the partial exams there will be the recovery of one or both partial ones.
- The student who has passed the exams may decide to take the recovery to raise the grade, with the understanding that the student will give up the grade achieved so far.
A student is graded as “non-assessable” if he / she has participated in assessment activities that represent ≤15% of the final grade, which translates into non-participation in either of the two partial exams.
* Student’s assessment may experience some modifications depending on the restrictions to face-to-face activities enforced by health authorities.
