General description Asignatura dedicada ao traballo de Laboratorio de Química Orgánica, con especial énfase en: técnicas de separación, aillamento e purificación; reactividade, síntese e caracterización de compostos orgánicos.
Contingency plan 1. Modificacións nos contidos.
No hai modificacions.

2. Metodoloxías.

*Metodoloxías docentes que se manteñen:
Todas (actividades iniciais, traballos tutelados, prácticas de laboratorio e proba mixta).

*Metodoloxías docentes que se modifican:
Todas as metodoloxías adáptanse á modalidade híbrida ou non presencial a través de Moodle e Teams e mantense a programación establecida no calendario de coordinación do Centro.
- Nos traballos tutelados mantéñense as entrevistas (individuais ou colectivas), que levaranse a cabo a través de Teams. Antes do inicio das entrevistas, os alumnos deberán completar e entregar a través de Moodle o traballo previo de preparación de cada práctica. Nas entrevistas discutiranse os aspectos experimentais (procedementos, técnicas de traballo e cuestións relativas á seguridade no laboratorio) e o profesor resolverá as dúbidas que poidan xurdir e avaliará o traballo previo realizado polo alumnado.
- Nas prácticas de laboratorio o alumnado elaborará un caderno de laboratorio para as experiencias programadas que inclúa (1) as correccións ao traballo previo que poidan derivarse das entrevistas, (2) a descrición dos procedementos experimentais adecuados para a preparación e purificación de compostos, (3) as respostas ás cuestións dos guións e (4) a interpretación dos espectros dos compostos implicados nos experimentos. O caderno de laboratorio entregarase a través de Moodle.
- A Proba mixta consistirá nun exame individual manuscrito, realizado a través de Moodle e, no caso de que a coordinación co resto das materias permítao, contémplase a súa realización adiantada durante o período lectivo.

3. Mecanismos de atención personalizada ao alumnado:
O seguimento personalizado realizarase a demanda do alumnado e, na medida do posible, no horario establecido para as titorías, a través do correo electrónico, a plataforma Moodle ou a ferramenta Teams. Para os estudantes con dedicación a tempo parcial ou modalidades específicas de aprendizaxe ou apoio á diversidade, facilitarase a atención personalizada dentro da flexibilidade permitida polos horarios de coordinación e os recursos materiais e humanos.

4. Modificacións na avaliación.
As contribucións á cualificación final das metodoloxías avaliables non se modifican

*Observacións de avaliación:
mantéñense todas as observacións incluídas na guía docente.

5. Modificacións da bibliografía ou webgrafía.
Non se realizan modificacións, todos os materiais necesarios atoparanse dispoñibles en Moodle ou mediante acceso aos recursos electrónicos dispoñibles na Biblioteca do Centro.

Methodologies
Methodologies Description
Introductory activities A session is programmed in a only group in which students will be exposed to the teaching methodology, planned activities and the evaluation criteria to be applied during the course program. Available resources will be presented on the website of matter and the dates on which the experiences and interviews will be conducted for students to organize their previous work indicated. Finally accurate information will be provided for students to start preparing for the first practice.
Supervised projects Tutored work includes assistance to 6 classroom sessions up to 2 hours, in which he will supervise and evaluate the work of the independent student for the preparation of the labs. It will be held one interview per lab. Before the start of the interviews, students must have completed the previous work every practice in the laboratory notebook, which can be replaced in some cases by a report of the preparatory work done to be delivered to the teacher. During interviews, the teacher will resolve the doubts that may arise and will evaluate the work done.
The preparation work practices should include calculations, experimental procedures and mounts necessary for the experience as well as an explanation of the mechanisms involved in the processes and solutions to questions of scripts to follow.
Laboratory practice There will be 13 sessions of up to four hours of work, where students will do some of the planned experiments are scheduled.

Prior to entering the laboratory, from a screenplay experience and bibliographic information available on the website of the subject, the student must work independently in the preparation of each experience way.
During laboratory sessions, simultaneously with the completion of the experiments so, students must develop a laboratory notebook, which collect the calculations, the experimental procedures and the necessary setups. The teacher will review the laboratory notebook for each student in each practice
After each practice, which may require several laboratory sessions, students must complete notebook with the results and conclusions, where the answers to the questions the script will include the structural elucidation of the compounds obtained and the data on its performance and purity.
Mixed objective/subjective test There will be a final written exam, in order to objectively assess the degree of assimilation and the applicability of the contents of the subject by students is scheduled in May.

Laboratory practice
Description
6 Interviews (with a total duration of 2 hours) are scheduled in which the teacher will carry out a follow-up, orientation and evaluation of non-face-to-face work done by the student for the preparation of laboratory sessions. Students should go to the interviews with a report of the preparation work done.

In addition, the student can receive personalized attention on any aspect of the subject during the teacher's tutoring schedule.

From the data provided in the statement (description and amounts of the starting materials and products structure synthesize) shall: (1) make all necessary calculations, (2) propose appropriate experimental procedures for the preparation and purification compounds, (3) describe the required assemblies and (4) propose reaction mechanisms that explain the processes involved. 30
 
Assessment comments
Attendance at the presentation session, the laboratory practicum,
the interviews (of the supervised projects) and the mixed test are mandatory.
To pass the course is necessary to obtain greater or equal to 5 out of 10 and a
minimum return of 30%. Students whose average yield exceeds 4.9 points and that
do not meet the minimum performance in any of the activities will be assessed
as "unfit" and receive the grade of 4.9. We will only qualify as
"not submitted" to students who have participated in activities that
add less than 25% of the final grade.

The marks obtained in interviews and in the labs will remain in
the 2nd opportunity at July 2021. On the second opportunity, the students who
have not passed the continuous evaluation of the practical laboratory work
should take a practical laboratory test. Students who have passed the
continuous assessment of practical laboratory work must complete a written
mixed test to establish 30% of the grade. In the second opportunity, the
students will be able to present themselves to a new evaluation of the mixed test
to establish 30% of the grade. According to the academic regulations, students
are evaluated on the second occasion only choose honors if the maximum number
of these not completed in full at the earliest opportunity.

With regard to the successive academic years, the process of
teaching and learning, including assessment, refers to an academic year and
thus begins again with a new academic year, including all activities and
evaluation procedures that scheduled for that course.

In the case of students with recognition of part-time
dedication and academic exemption of assistance exemption, the professor may
fully or partly exempt any member of the student body to attend the ongoing
evaluation process. Students that is in this circumstance must pass a specific
test that leaves no doubt about achieving the powers of matter on two
occasions.
