4) A) Explain the regiochemistry of the following bromination using key resonance structures (there should be three) and predict the final product. Hint: Drawing these resonance structures is key to tell you if this substituent will direct bromination ortho/para or meta (3 polnts for the correct product, 4 polnts for the resonance structures, 7 points total).

Imagine there is an enyzme that is critical for the progression of the viral disease Dramatic Chipmunk has. (Note: it is irrelevant which specific viral disease Dramatic Chipmunk has). Scientists know the substrates, products, and a chemical mechanism for this enzyme, but there are no known inhibitors. If an organic chemist is asked to synthesize some inhibitors, they will almost...
