Anhydrous AlCl_3 is used in Friedel-Crafts reaction because it is(A) Soluble in ether(B) Ionisable to Al and Cl ions(C) Electron rich(D) Electron deficient molecule
Anhydrous AlCl3 is used in Friedel-Crafts reactions because it is an electron-deficient molecule. Therefore, the correct option is (D) Electron deficient molecule.
In Friedel-Crafts reactions, AlCl3 acts as a Lewis acid catalyst, meaning it can accept a pair of electrons from another molecule, facilitating the reaction. Specifically, it acts to activate the electrophile, making it more reactive toward the aromatic ring. This electron deficiency is a key characteristic that enables AlCl3 to participate in the Friedel-Crafts reaction.
