11. For the CH4 molecule, VSEPR Theory states that: a. Hydrogen atoms will cluster together to get as far away as possible from the electron cloud of carbon b. A tetrahedral shape will form, because the electrons of the hydrogen atoms will repel each other, creating the maximum possible amount of space between each hydrogen atom c. A pyramidal shape will form because of a lone pair of electrons on the carbon d. This molecule is impossible 12. For the CH4 molecule, Valence Bond Theory states that: a. Carbon will form sp hybrid orbitals b. Carbon will form sp? hybrid orbitals c. Hydrogen will form sp hybrid orbitals d. pi bonds will form between carbon and hydrogen 13. Which atom or ion could not have the following electron configuration: 1s'2s 2p°3s°3p° а. Ar b. Cl c. S d. p3- 14. A substance is found to be soluble in water, but not conductive in solution. The substance is most likely: a. lonic b. Non-polar covalent c. Polar covalent d. Metallic

Decide how the sketches below would be listed, if they were listed in order of decreasing force between the charges. That is, select "1" beside the sketch with the strongest force between the charges, select "2" beside the sketch with the next strongest force between the charges, and so on. -2 -1 OO 1 (strongest) 2 3 4 (weakest) 1 (strongest) 2 3 4 (weakest) X 1 (strongest) 2 3 4 (weakest) 1 (strongest) 2 3 4 (weakest) ? 000 Ar
