Chemical Structure and Bonding
At the end of this curricular unit, students should have aquired knowledge and skills which will allow them to:
Apply general concepts of quantum mechanics
Predict atomic and mlecular properties
Predic Lewis Strucutures.
Predict electronic structure and molecular geometry through Valence Bond Theory and Molecular Orbital Theory
Predict molecular properties (bond order and distance, paramagnetism, acid/base behaviour, nucleofilicity and electrofilicity, ioniztion energy, electron afinity, conductor, semi-conductor or insulating properties, etc.)
Use Molecular Orbital Theory to predict and rationalize chemical reactivity in simple molecules.
