Q: Which of the following reactions is an example of Friedel-Crafts acylation?

Solution: Benzene + CH3COCl in AlCl3 is an example of Friedel-Crafts acylation, where an acyl group is introduced to the aromatic ring.

Steps: 5

Step 1: Understand what Friedel-Crafts acylation is. It is a chemical reaction that introduces an acyl group (like COCH3) to an aromatic ring (like benzene).
Step 2: Identify the reactants in the given reaction. In this case, we have benzene and CH3COCl (acetyl chloride).
Step 3: Recognize the role of AlCl3. It acts as a catalyst to help the reaction occur.
Step 4: Combine the reactants. When benzene reacts with CH3COCl in the presence of AlCl3, an acyl group is added to the benzene ring.
Step 5: Conclude that this reaction is indeed an example of Friedel-Crafts acylation because it involves the introduction of an acyl group to the aromatic ring.
