Question

During the electrophilic aromatic substitution of benzene with $Cl_2$ to strictly yield chlorobenzene, what is the precise catalytic function of the added anhydrous $FeCl_3$?

Answer: C

💡 Solution & Explanation

$FeCl_3$ is a strong, electron-deficient Lewis acid. It coordinates directly with the $Cl_2$ molecule, drawing electron density and heterolytically snapping the bond to release the highly reactive chloronium ion ($Cl^+$).
