Question

The function of anhydrous $AlC{l}_3$ in the Friedel-Craft's reaction is to

• A. Absorb water
• B. Absorb HCl
• C. To produce electrophile
• D. to produce nucleophile

Answer 1

The correct option is C To produce electrophile

The function of anhydrous $AlC{l}_3$ in the Friedel-Craft's reaction is to produce electrophile.
$C{H}_{3}Cl+AlC{l}_3\to C{H}_3^{+}+\left[AlC{l}_4^{-}\right]$
here $C{H}_3^{+}$ is an electrophile which attacks aromatic ring during friedel craft's reaction.
