Comment: Thanks for all your hard work in this class. I hope you've learned a lot and please let me know if I can help with any of the questions you missed here. Even though the course is over, it's never too late to learn. Part 1 of 5 - 10.0/ 10.0 Points Please show as much work as possible for full credit. Question 1 of 16 5.0/ 5.0 Points (a) Discuss the difference in the shapes of s and p orbitals. (b) How many electrons does each orbital hold? (c) Which of these orbitals do electrons occupy first? (d) Which of these orbitals has the electrons with the highest energy, assuming both orbitals are in the same energy level? Be sure to base your answer on what we discussed in THIS class and use the terminology from the materials in THIS course. Your answer must be sufficiently detailed to receive credit, and properly labeled according to the letters above.
Question 2 of 16
5.0/ 5.0 Points `A drug task force involving local, state, and federal officers raided a suspected illegal dealing facility. They ran a preliminary field test on a product they found that appeared to be crushed pills or powder, and it tested postitive as being cocaine. This was done using a test solution that turns blue if cocaine is present. However, the report indicates the result was actually a bluish-purple color, and the defense lawyer later used this to accuse the lab techs of using contaminated or wrong chemicals, and that they instead possibly used the test for morphine, which turns purple for a positive result. The difference here is that the defendant had prescriptions for morphine, which would prevent him from going to prison. The field test for morphine contains formaldehyde (CH2O, where C is the central atom). The test for cocaine contains chloroform (CCl3H, where C is the central atom). An independent lab tested the solutions used in the field test, and determined that there were no molecules present whose ELECTRON geometry were trigonal planar. So, does the defense have a case based on this evidence? What does this evidence prove? (Remember: The question asks about electron geometry, not molecular geometry.)
