5. How does protonation change the structure of carbonate? (adding an H+to CO32- )
6. Sulfur dioxide and carbon dioxide have somewhat different properties, in spite of the fact that both are triatomic molecules with two terminal oxygen atoms. Can you explain why they are as different as they are?
7. Because carbon tetrachloride is not soluble in water, a test tube containing the two liquids will form two layers. Predict which layer is on top and justify your answer. If molecular iodine is added to the test tube, predict which liquid layer will dissolve most of the iodine and justify your answer.
8. Consider the following organic molecules. What are the hybridizations around each carbon atom? What are the shapes around each carbon atom? You may want to number your carbon atoms for clarity. (CH4, C2H6,C2<>H4</>, C2H2, C33H6 )
