3. Consider the electrophilic aromatic substitution reaction below. Draw three resonance structures of the arenium cation intermediate resulting from para attack. Of these three, indicate one which would be a relatively stable resonance contributor. Finally, provide a possible justification for the fact that the major product here would be the para product, while the ortho product is formed as a minor product (only trace amounts of meta product are formed). Br2, FeBrz

9. Draw the three products made during this ortho-para directing reaction, keeping in mind that deuterium (D) is an isotope of hydrogen and reacts in much the same way as a hydrogen. OH HNO3 H₂SO4
Compound to can undergo another electro, cyclic reaction, thereby forming the skeletal structure of endiandic acid G. Add curved arrows to draw the mechanism for this process.
1. would you expect the relative rate of SE2 reactions to be faster or slower if a molecule of chlorine is used instead of bromine? Explain your reasoning? 2. why is the first step in an electrophilic aromatic bromination so much more endothermic than the first step in an electrophilic addition of alkene?

14. 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. butanone + CH.MgBr followed by acid 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.
