Example 8: SF Experiments show that this molecule has a seesaw shape. 10. Show, by writing orbital diagnams for the vatence electrons of the S atom in is ground and hybrid orbital states, how 4. p. and d orbitals can be combined to give a set of five sp3d hybrid orbituls (four bonding orbitals plus one lone pair). Electronic configuration of S(Z=) ground sate ⟶ hybrid orbitals 11. Now fill in the repon table for SF4​. 12. Remove a second white sphere and attached yellow sphere and replace them with a blue sphere (representing a second lone pair). 13. How many different models are possiblei 14. Draw a diagram of each model. Next to each diagram list the number of LP-LP. LP-BP. and BP-BP repulsions. Ignore repulsions at angles greater than 90∘. 15. Which is the preferred form, and what is its molecular geomety? Why? Example 9: BrF, Experimentally determined geometry shows T-shaped molecules with angles of 87.5∘. 16. Show, by writing orbital diagrams for the valence electrons of the Br atom in its ground and hybrid orbital states, how h. p. and d orbitals can be combined to form a set of five sp3d hybrid orbitals (three bonding orbitals plus two lone pairs). Electronic configuration of Br(Z=) ground state hybrid orbitals
17. Now fill in the repon table for BrF, Remove a third white sphere and attached yellow sphere and replace them with a blue sphere (representing a third lone pair). 18. How many different models are possible? 19. Draw a diagram of each model. Next to each diagram list the number of LP−LP,LP−BP, and BP-BP repulsions. Ignore repulsions at angles greater than 90∘. 20. Which is the preferred model, and what is its molecular geomedy? Why?
