|Faculteit||Wiskunde en Natuurwetenschappen|
|Vaknaam||Molecules: Structure, Reactivity, and Function|
|Periode||semester I a|
|Uitgebreide vaknaam||Molecules: Structure, Reactivity, and Function|
|Leerdoelen|| Upon completion of this course, the student should:
(1) be able to describe the orbital structure and the electronic 'aufbau' of small atoms and typical organic molecules made of these atoms at an elementary and qualitative level
(2) be able to classify any object with respect to a point group using its symmetry elements and to understand the basic elements of stereochemistry in terms of this knowledge concerning symmetry
(3) be able to explain which circumstances and structural properties of molecules are important in chemical reactions, based on the two standard substitution reaction mechanisms in organic chemistry; be able to steer the course of a nucleophilic substitution reaction by adjusting the reagents and reaction circumstances
(4) be able to qualitatively describe the structure and properties of (extended) pi-conjugated molecular orbitals and to describe the corresponding energy levels; be able to describe absorption and emission of light by molecules in terms of electron energy levels and transitions between them; be able to compare pi-conjugated systems and predict qualitative differences between such systems in terms of color, energy, reactivity; know the basic aspects concerning electrical conduction and transfer of energy in and between molecules
(5) be able to describe the materials that are subject of ongoing research in the field of organic electronics within our faculty – e.g. conjugated polymers, fullerenes, (carbon) nanotubes, graphene- and to describe the basic structure of devices like OLEDs and organic solar cells, in which these materials can be applied.
(6) be able to work in an academic chemical laboratory according to the rules and habits, with a focus on the following essential elements: planning, performing and reporting about an experiment, keeping a notebook, and handling waste properly
|Omschrijving|| Part 1. Molecular structure. Discussion from the perspective of organic bonds. Important aspects: Valence bond theory, molecular orbital theory, VSEPR, resonance structures, atomic orbitals, hybridization, molecular orbitals, Lewis structures, and symmetry/stereochemistry. (Vollhardt & Schore ‘Organic Chemistry’(V&S), Chapters 1, 2, 5; Atkins ‘Physical Chemistry’, Chapter 11).
Part 2. Based on SN1 and SN2 reactions, essential concepts such as reaction mechanism, transition state, intermediates, solvation, reactivity, and steric hindrance will be discussed. Furthermore, how to apply this knowledge to affect the course of a reaction. (V&S Chapters 6, 7).
Part 3. Molecular functionality. Opto-electronic functionality will be dealt with mainly, as an example of molecular functionality. First, molecules with delocalized -systems will be introduced (V&S Chapters 14, 15). Next, a diversity of electronic properties and functionalities of more complex structures will be dealt with (incl. acenes, porphyrins, molecular carbon, and conjugated polymers). This part of the module ends with an introduction to ongoing research in the field of organic electronics within the faculty and (possible) applications of organic electronics in practice. (Reader)

((The possibility to hand in homework will be given a number of times during the course. This material will be corrected and graded. Half way during the course, there is a midterm exam. The course includes two compulsatory practical courses. At the end of the course there is the final exam.))

((c) Final grade for the course: ProgressWWW calculates automatically: FGC = (2*FGT + mean P1,P2)/3; in which FGC is the final grade of the course. Thereafter, the teachers round the grade to 0.5 point precision, except the grade 5.5 (not given) Hence, three grades go to the educational office (FGT, P1, P2) and ProgressWWW calculates the exact value of FGC automatically, after which the teachers round this grade to 0.5 point precision. The study points (ECTS) for the course are only given after all three grades of the course (FGT, P1, P2) are of sufficient quality.)

(a) Final grade theory part (FGT):
If FE>=4½, then FGT = max(FE, 0,2*HW + 0,8*FE, 0,2*MT + 0,8*FE, 0,2*HW 0,2*MT + 0,6*FE), with FGT as final grade theory part, FE as grade for the final exam, HW the mean grade for home work, and MT as grade for the midterm exam.
FE>=4½ means that a minimum 45 of the 100 points have to be reached.
In the ‘max’-formula homework and midterm exam grades are counted in the most favorable way for the student: either only HW, or only MT, or both grades for HW and MT.
The FGT (with 0.1 precision) goes into ProgressWWW separately from the grades on the two practicums.
In case of a re-exam, the homework and midterm exam results are no longer considered in the calculation of the FGT.
(b) Two (final) grades on the practicums:
A minimum grade of 6 for each of the practicums (P1,P2) is necessary to finish the course as a whole.
P1 = mean grade for both experiments of the first practicum (experiments are graded with 0.5 point precision, except the grade 5.5 (not given)
P2 = grade for the second practicum (again with 0.5 point precision and no 5.5)
The grades for practicums P1 and P2 go into ProgressWWW separately.
