Question

Catalyst used in Friedel-Craft's reaction is:

• A. $Al{Cl}_3$
• B. Anhydrous $Al{Cl}_3$
• C. $Fe{Cl}_3$
• D. $Zn{Cl}_2$

Answer 1

Answer: (B), (C)

$Fe{Cl}_3$
Anhydrous $Al{Cl}_3$

Catalyst used in Friedal Craft reaction is anhydrous $AlC{l}_3$.

Alkylation involves the alkylation of an aromatic ring with an alkyl halide using a strong Lewis acid, such as aluminium chloride, ferric chloride,

In friedel crafts alkylation, benzene (and its derivatives) is alkylated with alkyl

halide to form alkyl benzene.
In Friedel crafts acylation, benzene (and its derivatives) is acylated with acyl halide to form acyl benzene.
