You should assume than an E2 mechanism is observed.
An acid anhydride in the presence of AlCl3 will result in the electrophilic addition of the substituted acylium ion to the aromatic ring. The iodine is deactivating, but and directs substitution ortho- and para- through resonance interactions with the ring.
That is correct!
Sorry, that is not correct. You should modify your
structures and try again. If cis-trans-
stereochemistry is required, please make sure you have
drawn the appropriate isomer using the "wedge bonds".
Note: Nitro groups are shown
using two double-bonded oxygens
and sulfonic acids with two double-bonded oxygens and an OH.
