Name:_______________________ Per:_____ Seeing & Drawing Molecules in 3-D Molecule 1. H20 (water) 2. CH4 (methane) 3. NH3 (ammonia) 4. H2S (dihydrogen Sulfide) 5. HBr (Hydrobromic Acid) 6. CO2 (Carbon Dioxide) 7. O2 (oxygen) 8. N2 (nitrogen) 9. CH3OH (methyl alcohol) A. Draw the Lewis Dot Structure B. Re-draw your Lewis structure showing correct 3-D VSEPR Shape C. Name VSEPR Shape Bent Molecule A. Draw the Lewis Dot Structure B. Re-draw your Lewis structure showing correct 3-D VSEPR Shape C. Name VSEPR Shape 10. Cl2O (dichlorine monoxide) 11. PF3 (phosphorus trifluoride) 12. CHCl3 (chloroform) Questions: 1. Identify the following terms on the Lewis dot structure below: Lone pairs of electrons & bonded pair of electrons. 2. Why aren’t all molecules the same shape? 3. Both H2O and CO2 have 3 atoms ( 1 central and 2 on the outside). Why are they different shapes? 4. What affect do the lone pairs of electrons have on the overall shape of the molecule? Why? 5. Why are you unable to make ionic compounds using the model kits? 6. Complete the chart: 4 Main VSEPR Shapes Linear A Bent Pyramidal Tetrahedral Or X # Atoms bonded to central atom # lone pair electrons on central atom Common molecular examples:
