Nat -OET ethanol This reaction involves two successive Michael reactions, and has the following steps: 1. Deprotonation forms enolate ion 1; 2. The first Michael reaction forms enolate ion 2; 3. The second Michael reaction forms enolate ion 3; 4. Protonation leads to the final product. Write the mechanism out on a sheet of paper, and then draw the structure of enolate ion 2. • You do not have to...

During electrophilic aromatic substitution, a resonance-stabilized cation intermediate is formed. Groups, already present on the benzene ring, that direct ortho/para further stabilize this intermediate by participating in the resonance delocalization of the positive charge. Assume that the following group is present on a benzene ring at position 1 and that you are brominating the ring at positon 4. In the box below draw the structure of the resonance contributor that shows this group actively participating in the charge delocalization. -OCH3...
