1. Draw the Lewis structure of ethylene diamine, en. Be sure to include all atoms, bonds and lone pairs. Give the bond angles around each central atom (4 points). 2. Draw the skeletal formula of the complex ion in [Cr(en)3]Cl3 3HO using wedge and dashed bonds as required. Clearly indicate and name the coordination geometry about the chromium center. (Hint: https://en.wikipedia.org/wiki/Skeletal formula) (4 points). 3. What do chemists call the waters in the following formula: [Cr(en)3]Cl3 3HO (2 points) Should you include the waters when calculating FW? Why or why not (2 points)? 4. Would removing the waters influence the structure of the metal center shown in your answer to # 2/3? Yes/No? Why or why not (3 points)?
