Presentation Transcript

  1. Drill: • Carbon Monoxide Reading:(10 min) • Read the Carbon Monoxide Reading and answer the following questions. • Why is carbon monoxide so deadly? • What about carbon dioxide? Does it have the same effect?

  2. Objective: • Swbat: • Determine molecular shapes in order to predict bond angle and polarity by constructing covalent structures.

  3. SAT Enrichment: … and … would form a stable compound. • Sodium … Calcium • Lithium … Potassium • Nitrogen … Krypton • Aluminum …. Cesium • Magnesium … Oxygen

  4. Extension: • Last Class • Oil and Water Extension from last class • Soap Molecule Simulation: http://intro.bio.umb.edu/111-112/111F98Lect/soapandoil.html

  5. Engagement: • Polarity: • “Like Dissolves Like” (http://www.jce.divched.org/JCESoft/CCA/pirelli/pages/cca2like.html)

  6. Covalent Structures How to determine the structure of a compound.

  7. Class work Exploration: • Covalent Structure worksheet! 30 min

  8. Explanation: • Molecular Model Pre-Lab! 30 min

  9. Summary • Did we accomplish the objective? Explain. • How can you determine the structure of a compound using the NASL method? • What criteria would you assess to determine the polarity of a compound by knowing its structure? • Homework: • Instructional Fair pages 41 and 42

  10. Drill: • Draw the Lewis dot structure of the following compounds and determine their polarity: • CCl4 • AlCl3 • Objective: • Swbat: • Determine molecular shapes in order to predict bond angle and polarity by constructing covalent structures.

  11. SAT Enrichment: The forces of attraction that hold crystal together are called… • Ionic • London dispersion • Covalent • Electrovalent • Metallic

  12. Explanation • Molecular Model Lab 30 min

  13. Exploration: • VESPR –Theory • Teacher: (construct sample models for each shape (linear, bent, trigonal planar, trigonal pyramidal, tetrahedral). • Molecules are three dimensional and the electrons spread out to minimize their interactions (like charges repel). • Once the Lewis structure is drawn, it is possible to use the VSEPR Theory to predict the molecule’s shape.

  14. Exploration: • If the molecule is symmetrical along each axis, it is nonpolar. • If the molecule is asymmetrical along any of those axes, it is polar.

  15. VESPR-Theory • Complete the worksheet: 30 min

  16. Summary: • Did we accomplish the objective? Explain. • Identify the three types of hybridization and the types of bonds associated with them. • What criteria would you assess to determine the bond angle of a compound using the hybridization?

  17. Homework: • Out Spot: • Read the “Out Spot” worksheet and answer the hw question. • This homework assignment is an individual assignment. • If two homework answers are the same it will be assumed that you cheated. • Exit ticket: Covalent Structure
