Respond to the following discussion questions: 1. Do all molecules obey the octet rule? If No, give at least three examples of molecules that are exceptions to the octet rule and explain in detail why they do not obey 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).
