Question

Which of the following is used as a catalyst in Friedal kraft's alkylation reaction?

• A. Anhydrous $AlC{l}_3$
• B. $NaCl$
• C. $BeC{l}_2$
• D. $MgC{l}_2$

Answer 1

The correct option is A Anhydrous $AlC{l}_3$

Anhydrous $AlC{l}_3$ is used as a catalyst in Freedal kraft's alkylation reaction to initiate the reaction and for the generation of chlorine cation.$AlC{l}_3$ reacts with chlorine Molecule and forms Chlorine cation.
$AlC{l}_3+C{l}_2\to AlC{l}_4^{-}+C{l}^{+}$
Hence option A is correct.
