The curved arrow notation for the conversion of one of the ethanoate anion’s resonance structures into the other and the resonance hybrid is to be drawn. Concept introduction: The curved arrow illustrates the electron movement necessary to change one resonance structure into another. The ethanoate anion has two resonance structures. Each resonance structure has a negative charge on a different oxygen atom. This indicates that the negative charge is delocalized over the two oxygen atoms. Since each oxygen has a -1 charge in one structure and a zero charge in the other, the resonance hybrid charge is represented by a partial negative charge symbol -δ .

For each reaction below, decide if the first stable organic product that forms in solution will create a new CC bond, and check the appropriate box. Next, for each reaction to which you answered "Yes" to in the table, draw this product in the drawing area below. Note for advanced students: for this problem, don't worry if you think this product will continue to react under the current conditions - just focus on the first stable product you expect to form in solution. ?

Predicting As the lead product manager at OrganometALEKS Industries, you are trying to decide if the following reaction will make a molecule with a new C - C bond as its major product: H₂N O H 1. ? 2. H3O+ If this reaction will work, draw the major organic product or products you would expect in the drawing area below. If there's more than one major product, you can draw them in any arrangement you like. Be sure you use wedge and dash bonds if necessary, for example to distinguish between major products with different stereochemistry. 0 If the major products of this reaction won't have a new CC bond, just check the box under the drawing area and leave it blank. فا Explanation Check Click and drag to start drawing a structure.
