Post-Lab Questions
Directions: Answer the following questions, show work for all calculations. Work must be shown to receive credit for calculations. All questions are weighted equally.
- Define the following terms:
- covalent bond:
- valence electrons:
- octet rule:
- bonding electrons:
- lone pair electrons:
- charge cloud:
- electron geometry:
- molecular geometry:
2. Which molecules from this lab had lone pairs on the central atom? How did lone pairs affect the molecular shape compared to the electron geometry?
3. Draw the Lewis Dot structures for CH₄, NH₃, and H₂O. Why do the bond angles decrease?
4. Compare the flexibility & rigidity of your structures. Are there any noticeable differences in the flexibility & rigidity between the molecules containing single, double, & triple bonds?
5. How does the modeling kit help you visualize molecular structures differently than the Lewis structures alone?
