Chemical Structure and Bonding A


At the end, students should have acquired knowledge and skills which will allow:

To apply general concepts of quantum mechanics

Predict atomic and molecular properties

Predict Lewis Structures.

Predict electronic structure and molecular geometry through Valence Bond Theory and Molecular Orbital Theory

Predict molecular properties (bond order and distance, paramagnetism, acid/base behavior, nucleofilicity and electrofilicity, ionization energy, electron affinity, etc.)

Teaching method

Theoretical classes (2 x 1 hour weekly online), theoretical-practical classes (1.5 hours per week in person and 1.5 hours per week online), use of specific software to visualize molecular orbitals.

Evaluation method

The final grade is obtained by the weighted average between the two individual assessment tests (75%) provided that the average rating of the two tests is equal to or greater than 9 values, the group problem solving sessions (12.5%) and the mini-tests performed on the moodle platform (12.5%). The student will be approved if, after this weighted average, he/she obtains a classification ≥ 9.5

The student who does not obtain a classification ≥ 9 in the average of the two individual tests, will be evaluated in a final exam. For students who pass in the final exam (grade ≥ 9.5), the grade obtained in this exam will be the final grade for the course.
