A) Practice making Lewis structures using the “Making Molecules Simulator” from Cal Poly:
Use the molecule builder section.
Make 5 structures: Hydrogen Peroxide, Formaldehyde, Dimethyl Ether, Acetic Acid, and one of your choice (can be a free experiment one not found on the list). Take screen shots of each one once you have completed them.
B) Write resonance forms for these common molecules:
- Nitrate ion
- Acetate ion
C) Calculate bond energies for these bonds:
- C-H in CH
- P-Cl in PCl5
D)For which of the following substances is the least energy required to convert one mole of the solid into separate ions?
E)Use the Molecule Shape simulator to simulate a molecule. Starting with the central atom, click on the double bond to add one double bond. Then add one single bond and two lone pairs. Check out all of the geometry by rotating. Name the electron group geometry and molecular structure and predict the bond angle. Use the check boxes at the bottom and right of the simulator to check your answers.
Use the Molecule Shape simulator to explore real molecules. On the Real Molecules tab, select H2O. Write two sentences explaining the difference between real and simulated H2O.
