Experiment #11 Molecular Geometry PreLab. 1. Draw the Lewis structures for the following molecules. 2. In problem number 1, which molecules are polar? 3. In problem number 1, which molecules have polar bonds? Questions 4-13
1. Draw the Lewis structures for the following maleculest b. SiBre \( \quad: \underset{B r}{*}-\frac{1}{1}=\frac{1}{B r}-B r \) c. \( \mathrm{AsF}_{3} \). d. \( \mathrm{NO}_{2}{ }^{+} \) e. \( \mathrm{GaH}_{4}^{-} \) \[ \begin{array}{c} +4-6-1+1 \\ +4 \end{array} \]
Use the Lewis structures from the previous page to answer the following questions: 2. In problem 1 , which molecules are polar? 3. In problem #1, which molecules have polar bonds? 4. Molecular geometry of \( \mathrm{SiBr}_{4} \) 5. Hybridization of \( \mathrm{Si} \) in \( \mathrm{SiBr}_{4} \) 6. Number of lone e pairs on \( \mathrm{As}_{\text {in }} \mathrm{AsF}_{3} \) 7. Hybridization of \( \mathrm{As} \) in \( \mathrm{AsF}_{3} \) 8. Molecular geometry of \( \mathrm{AsF}_{3} \) 9. Electron geometry for \( \mathrm{AsF}_{3} \) 10. Number of \( \sigma \) bonds in \( \mathrm{NO}_{2}^{+} \) 11. Number of \( \pi \) bonds in \( \mathrm{NO}_{2}^{+} \) 12. Bond angle between the atoms in \( \mathrm{NO}_{2}^{+} \) 13. Total number of valence clectrons for \( \mathrm{GaH}_{4} \)
