Which catalyst is used in Friedel-craft alkylation reaction
Correct answer: B. AlCl3
- A. MgCl2
- B. AlCl3
- C. NaF
- D. CaCl2
Explanation
Friedel-Crafts alkylation is an electrophilic aromatic substitution reaction that utilizes an alkyl halide and a Lewis acid, typically AlCl3, to produce an alkylbenzene. In this reaction, the alkyl halide reacts with the Lewis acid to form an electrophile, which then attacks the aromatic ring to create a new carbon-carbon bond. Option B, AlCl3, is the correct catalyst for this reaction. Options A, C, and D are incorrect as they do not play the role of the Lewis acid catalyst in Friedel-Crafts alkylation reactions.
