Question

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 • 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.

Answer 1

Answer:

See explanation

Explanation:

In electrophillic aromatic substitution, an electrophile attacks the aromatic ring and resonance structures are created.

We know that the nature of the substituents already present in the ring determines the position to which the incoming substituent is directed.

-OCH3 is an ortho-para director. If the -OCH3  is present at position 1 and the ring is brominated at position 4, the resonance structures shown in the image attached are observed.
