2.The following concern atomic orbitals. a. Plot the energy levels of the atomic orbitals (1s, 2s, etc.) for hydrogen. b. Draw the basic shapes of these orbitals. Be sure to label your x-y-z axes. c. Draw the basic shape and probability of an H2 molecule in its ground state.

3. Build the following molecules in WebMO: H2, acetic acid, benzene, cyclohexane, bromoethane, and two other real molecules of your choice. Use Screen Capture (Alt-Print Screen in Windows) to copy images of the molecules. Paste them into a document showing your work. H2 Acetic Acid Benzene

4. Find the PM3 geometries (bond distances, angles, etc.) and dipole moments of the two conformers of formic acid and compare with Hartree Fock results (optimize the structures in both cases). PM3 and Hartree- Fockare the “Theory “that you would choose in Webmo. You can leave “Basis Set” to the default value.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
