Q: Which of the following reactions involves a Friedel-Crafts acylation?
Solution: Friedel-Crafts acylation involves the reaction of benzene with an acyl chloride (like CH3COCl) in the presence of a Lewis acid.
Steps: 4
Step 1: Understand what Friedel-Crafts acylation is. It is a chemical reaction that introduces an acyl group (like -COCH3) into a benzene ring.
Step 2: Identify the reactants needed for Friedel-Crafts acylation. You need benzene and an acyl chloride (for example, CH3COCl).
Step 3: Recognize the role of a Lewis acid in this reaction. A Lewis acid (like AlCl3) is used to help activate the acyl chloride so it can react with benzene.
Step 4: Look for a reaction that includes benzene, an acyl chloride, and a Lewis acid in the options provided.
