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....

+ H+ Electrophilic aromatic substitution is a two-step process. In the first step an electrophile, here generically shown as Y , reacts with the aromatic ring to form a resonance-stabilized carbocation intermediate. In the second step, loss of a proton from the site of attack restores aromaticity to the ring and completes the reaction. Draw curved arrows to show the movement of electrons in this step of the mechanism. Arrow-pushing Instructions no XT + H H- A

Select the statement that is true about the electrophilic aromatic substitution and the molecule shown. Select one: a. The carbonyl carbon is activating. The CH, group is deactivating. Therefore, the CH, group will dictate the location of the reaction. b. Both groups are activating. Therefore, the reaction will occur ortho to both groups. c. The carbonyl carbon is deactivating. The CH2 group is activating. Therefore, the CH2 group will dictate the location of the...
