Haloarenes may show friedel-crafts reaction
WebThe picture above shows the Friedel-Crafts Reaction, both alkylation and Acylation undergone by Benzene.You can notice that in both these reactions (alkylation and acylation), the hydrogen atom which was at first attached to the aromatic reaction was replaced by an electrophile Aluminium trichloride (AlCl 3).In Friedel-Crafts reactions … WebAn alkyl group donates electrons to the ring by hyperconjugation, making it more reactive than normal benzene. The acyl group actually withdraws electrons from the ring by …

The Friedel–Crafts reactions are a set of reactions developed by Charles Friedel and James Crafts in 1877 to attach substituents to an aromatic ring. [1] Friedel–Crafts reactions are of two main types: alkylation reactions and acylation reactions. Both proceed by electrophilic aromatic substitution.
The replacement of an atom or group of atoms by an electrophile in a molecule is called an electrophilic substitution reaction. Haloarenes undergo the usual electrophilic … See more The species which are electron deficient are called electrophiles. An electrophile can be a positively charged or neutral species (having a vacant orbital).
