Last chapter we studied ionic compounds and their naming conventions. In this next unit, we will examine the how and why of molecular structures. What makes one bond possible and others impossible? Why do atoms bond together in certain ratios? What constitutes an ionic bond versus a covalent bond? These questions and more will be resolved, hopefully, by the time we complete this unit. | |||||

| Dispersion Force | Double Bond | Hybridization | Triple Bond | ||
| Nonpolar Covalent Bond | Electronegativity | Polar Covalent Bond | Resonance | ||
| Single Bond | Unshared Electron Pair | ||||
| 2) Compare and contrast ionic, polar covalent, and non polar bonds. | |||||
| 3) Explain what happens when a coordinate covalent bond is made. | |||||
| 4) Correctly name molecules and acids. | |||||
| 5) Draw electron dot diagrams and use them to explain ionic and covalent bonding. | |||||
| 6) Understanding the various ways in which single, double, triple, and coordinate covalents are constructed. | |||||
| 7) Gain a rudimentary understanding of orbital theory, the 3-dimensional implications of hybridization, and the VSEPR theory. | |||||
