The best arrangement for the carboxyl group with respect to its formal charge is to be determined. Concept introduction: For many molecules, it is impossible to explain all properties by a single Lewis structure. In such cases, more than one Lewis structures are drawn to explain the properties. Such structures of a compound are called resonating structures and the phenomenon is called resonance. Due to their attraction towards electrons, ions and molecules acquire some charge which is called formal charge. Formal charge is given by: Total number of valence electrons in a free atom - total number of associated electrons

Be sure to include any relevant stereochemistry in the product structure. + SK F Br + (b) In which solvent would this reaction proceed the fastest (Circle one) Methanol Acetone (c) Imagine that you are working for a chemical company and it was your job to perform a similar reaction to the one above, with the exception of the S atom in this reaction being replaced by an O atom. During the reaction, you observe the formation of three separate molecules instead of the single molecule obtained above. What is the likeliest other products that are formed? Draw them in the box provided.

3. For the reactions below, draw the arrows corresponding to the transformations and draw in the boxes the reactants or products as indicated. Note: Part A should have arrows drawn going from the reactants to the middle structure and the arrows on the middle structure that would yield the final structure. For part B, you will need to draw in the reactant before being able to draw the arrows corresponding to product formation. A. B. Rearrangement ΘΗ
