1. Do all molecules obey the octet rule? If No, give at least three examples of molecules that do not obey the octet rule/exceptions to the octet rule.
2. What is the difference between electron-domain geometry and molecular geometry of a molecule? Give examples.
3. Discuss how “Bond dipoles” in molecules can be used to determine polarity in molecules. (Note: Clear illustration MUST be used to explain this).
4. Discuss the following about the following molecules:
TeCl2:
Describe the molecular geometry of the whole molecule
Polarity of the whole molecule
Hybridization of the central atom (Te)
PBr5:
Describe the molecular geometry of the whole molecule
Hybridization of the central atom (P)
NH4+:
Describe the molecular geometry of the whole molecule
Describe the polarity of the whole molecule
Hybridization of the central atom (N)
