Please help... Need a detail Mechanism of this reaction. Thanks... 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...

+ 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
Friedel - Craft Acylation Synthesis of 4-Methoxiacetophenone Background Information 1.- What is an electrophilic aromatic substitution? 2.- Give three examples of activating groups. Explain why they activate the ring for substitution. 3.- Give three examples of deactivating groups. Explain why they deactivate the ring for substitution. 4.- Describe the difference between a Friedel-Craft alkylation and Acylation. Synthesis of 4-Methoxiacetophenone For this Friedel-Craft acylation we will react Anisole with Acetic Anhydride. Write the mechanism and the structure of the final product....
a) Complete the generic mechanism for an electrophilic aromatic substitution (EAS) reaction using El as the electrophile and show how the sigma complex is resonance stabilized. Use curved arrows to show the mechanism and the conversion between resonance structures. Make sure to add any missing charges. Note the use of a generic base in the last step. b) Label the reaction coordinate diagram for a typical EAS reaction shown below by correctly placing the letter for each structure on the...
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:

Aromatic heterocycles also undergo electrophilic aromatic substitution reactions. When furan is treated with an electrophile, the electrophile is installed only at the C-2 position. Explain why this reaction occurs only at the C-2 position, rather than the C-3 positions.(explain in words and resonance structures) Question 2 (10 pts). Aromatic heterocycles can undergo EAS reactions. When furan (below) is treated with an electrophile, an EAS reaction occurs in which the electrophile is installed only at carbon 2, not carbon 3. Explain...
