2. Use the atomic skeleton of a molecule below to answer the following questions. F FS F N₁ C₁-C2 H H-O-C N₂ H CA N H C5 F₁- C C6-H -C C₁-H H F a) How many valence electrons are in the molecule? b) Use these valence electrons to complete the above structure so that EVERY atom has zero formal charge (this will mean adding lone electrons and multiple bonds to some atoms). Be sure to show how you know the formal charge of each atom in the structure. c) Give the electron domain geometry and the molecular geometry for: (a) Carbons labeled 1-8, (b) Nitrogens labeled 1-3, (c) Oxygen and (d) Sulfur. Explain how you came to your answer.
