a. Write a second resonance structure for the following carbocation. b. Is the charge shared equally by both allylic carbons? If not, which one bears more of the charge? Select the single best answer. Both carbocations carry the same amount of charge. The structure on the left in Part 1 contributes more to the resonance hybrid. The structure on the right in Part 1 contributes more to the resonance hybrid.
17. a. Label the reactive features, highlight the most reactive one, then highlight what it needs. Also, state if the reaction will start to create a carbocation, carbon radical, or carbanion, or will cause loss of aromatic character. If a carbocation, carbon radical, or carbanion starts to develop, label where that will occur. CH3 with Cl, and FeCl, CH2 CH3 b. Use mechanism arrows to illustrate the reaction that occurs. c. If applicable, use stabilization resources to deal with the carbocation, carbon radical, or carbanion that starts to develop during the reaction, and draw the structure of any resonance-stabilized intermediate. d. Continue labeling and diagramming the reaction until you find the major stable product(s). e. Finally, state the stereochemistry of the major product(s) and use either Fisher projection or perspective formula representations to illustrate that stereochemistry.
