1,3–Dimethoxybenzene (below) is very reactive toward
electrophilic aromatic substitution. Draw a complete mechanism for
the following nitration reaction making sure you include details of
formation of the required electrophile and all possible delocalized
structures for the intermediate cation. Provide a brief explanation
for why only the pictured product is formed:
Homework Answers
In electrophilic aromatic substitution reaction, as OMe are the
donating groups, therefore incoming NO2 electrophile will go on the
ortho and para to the methoxy group. Another forming products are
not that much stable. Bcoz three group are at the adjacent
positions. Therefore this product is not forming.

Electrophilic aromatic substitution describes the reaction where a hydrogen from a benzene ring is replaced by an electrophile. Halogenation, nitration, sulfonation, alkylation and acylation are all possible using this type of reaction. The electrophile attacks the pi electrons of the aromatic ring, yielding a benzenonium ion. The substituted aromatic product is obtained when a proton is lost, restoring the aromatic system. If there is a substituent on the aromatic ring...
