Section 3: 3a. Draw the best Lewis structure for the following two acid molecules (Hint! the acidic H is bonded to O in an acid molecule). Evaluate each atom in both molecules using formal charge, showing all your math work as well as your formal charge answers. HCIO4 CH3COOH b. The N3 ion can be drawn with two double bonds, or with a single bond and a triple bond. Both structures satisfy the octet rule. Use formal charge to evaluate the structures. Which do you think is the better choice? Give reasons to support your choice. Section 4: 4. Chloromethane, CH;Cl has many uses, one of which is an extractant for oils. Chemists often use the phrase "like dissolves ike" to summarize the observation that polar solvents prefer to interact with polar molecules, and nonpolar solvents prefer to interact with nonpolar molecules. Use this fact to explain why Chloromethane, CH3CI, is a good extractant for oils. Oils are nonpolar substances containing carbon and hydrogen atoms. In formulating your answer, include the following information below: a. What is the molecular geometry (shape) of the CH3CI molecule? b. Is CH;Cl polar or non-polar? How did you determine that? Mark the polarity on the CH;Cl molecule using the molecular dipole moment arrow. c. Explain why CH3CI would make sense to extract non-polar substances, such as oils.
