Ans: The Amino group attacks the Lewis acid to form the acid-base complex in which the aromatic ring is strongly deactivated.
Note: Aniline does not undergo friedel crafts acylation because reagent AlCl3(which is a lewis acid) which is used as a catalyst being electron deficient acts as a lewis base.

Friedel-Crafts acylation reactions cannot be performed on aniline because: The amino group attacks the Lewis acid to form an acid-base complex in which the aromatic ring is strongly deactivated. The amino group is strongly activating and multiple substitutions occur on the aromatic ring. The amino group is strongly deactivating preventing any substitution on the aromatic ring. The amino group gets acylated instead of the aromatic ring. Which of the following produces no reaction? -O'Na+ + H2O CH3 Li+...

Friedel-Crafts Acylation of Ferrocene "riedel-Crafts reactions are examples of electrophilic aromatic substitution reactions. The eaction involves the substitution of hydrogen on the aromatic ring system by an electrophilic arbon species forming a new carbon-carbon bond. Friedel-Crafts reactions may be used to ntroduce either an alkyl or acyl group. Ferrocene does not undergo addition reactions typical of cyclopentadiene, but undergoes Electrophilic aromatic substitution. The Friedel-Crafts acylation reaction of ferrocene involves he addition of the acylium cation to one of the carbon...
