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...

Nitration of phenols is a classic example of an electrophilic aromatic substitution reaction. a) Why does the nitration of phenol (hydroxybenzene) proceed only in the ortho- and para-positions on the ring? b) Draw the resonance structures that highlight the ortho- and para-directing nature of hydroxy substituents. Make sure to include the structures that showcase the movement of the charges in the ring.

When naphthalene undergoes an irreversible electrophilic aromatic substitution, the major product is the kinetic product, which proceeds through the most stable arenium ion intermediate. With this in mind, draw the curved arrow mechanism for the first step of the electrophilic aromatic substitution of naphthalene with l^+ generated from l_2 and CuCl_2. If you predicted the correct regiochemistry in the first step, then you can draw the curved arrows and a resonance structure in step 2 with an unbroken benzenoid ring....
