- 87 - Chapter 9 Chemical Bonding Theories and Molecular Structure COURSE OUTCOMES ADDRESSED IN THIS CHAPTER: I. Thinking and decision-making A. Gather and comprehend information from reading texts, handouts, lecture manual and lecture notes, and making observations: 1. memorize key information and put it into an appropriate context 2. translate information from one form to another(written words to symbols, diagrams, physical actions, etc.) B. Analyze information: 1. solve a problem/come to a conclusion by working inductively or deductively 5. recognize assumptions 6. identify errors in reasoning C. Apply general principles to specific situations III. Scientific competence: A. Apply the reasoning process used in science: 1. define and classify information unique to chemical systems 2. recognize patterns within chemical systems and be able to compare these PERFORMANCE CRITERIA FOR ABILITY OUTCOMES: Chapter 9 (Chemical Bonds: General Concepts) 1. Be able to define or explain: ionic bonding cation single bond covalent bonding anion double bond electronegativity valence electrons triple bond dipole isoelectric species polyatomic ion polar molecules resonance structures polar covalent bond bond angle nonpolar covalent bond VSEPR Theory molecular geometry electronic geometry tetrahedron coordinate covalent bonding trigonal pyramid shared pairs of electrons trigonal bipyramid lone pairs of electrons see-saw shape octrahedron 2. Relate relative electronegativity with position in the periodic table. 3. Predict on the basis of their positions in the periodic table those combinations of elements that form compounds of ionic character and those that form compounds of covalent character. 4. Determine whether certain molecules contain polar or non- polar covalent bonds.

- 88 - 5. Be prepared to draw Lewis Structures for common atoms, ions and molecules. 6. Be able to draw the appropriate resonance structures for a given species. 7. Distinguish between lone pairs and shared pairs of electrons. 8. Explain why unshared electron pairs exert greater repulsive interaction on other pairs than do shared electron pairs. 9. Be able to successfully draw the Lewis structure for a molecule or polyatomic ion. 10. Predict the geometrical structure of a molecule or ion from its Lewis structure. 11. From the geometry of a molecule be able to predict if the molecule is polar or non-polar. 12. Be able to recognize the different geometric structures and name each one.
