Questions & Step-by-Step Solutions
Which of the following compounds can undergo Friedel-Crafts alkylation?
Correct Answer: Benzene
Step 1: Understand what Friedel-Crafts alkylation is. It is a chemical reaction that adds an alkyl group to a benzene ring.
Step 2: Identify the starting material. The starting material must be benzene or a compound that can form a benzene-like structure.
Step 3: Check if the compound has a suitable alkyl halide. Friedel-Crafts alkylation typically requires an alkyl halide (like an alkyl chloride or bromide).
Step 4: Ensure the presence of a strong Lewis acid catalyst, such as aluminum chloride (AlCl3), which is necessary for the reaction to occur.
Step 5: Determine if the compound can stabilize the carbocation formed during the reaction. If the alkyl group can stabilize the positive charge, the reaction is more likely to occur.
