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. -NH2 • You do not have to consider stereochemistry. • You do not have to explicitly draw H atoms. • Do not include lone pairs in your answer. They will not be considered in the grading.

Please indicate which ONE specific structure is the answer. Thank you!!
Expert Solution
Step 1
An electrophile attacks at more nucleophilic site. In case of electron donating group, ortho and para positions are the one carrying negative charge in resonating structure and therefore they are ortho para directing.
