11. For the BF3 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 trigonal shape will form, because the electrons of the fluorine 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. A trigonal shape will form with angles of 120 degrees. 12. For the CH4 molecule, Valence Bond Theory states that: a. Hydrogen will form sp³ hybrid orbitals. b. Carbon will form sp² hybrid orbitals. C. Carbon will form sp³ hybrid orbitals. d. pi bonds will form between carbon and hydrogen.
