1. Which, if any, of the molecules in Exercise 1 had resonancestructures? How many resonance structures did each molecule have?2. Both chlorine and fluorine are represented by a green modelingpiece that has 4 holes. Is using the same piece for two differentatoms acceptable? Why or why not? 3. List all of the possiblegeometric structures of a molecule that contains two atoms. 4.Explain why only the lone pairs on the central atom are taken intoconsideration when predicting molecular shape. What molecules fromthe lab activity are exceptions to this?
