Question
**Question:** Predict the major product. Either describe or upload an image. **Chemical Structure Provided:** A reaction is depicted where a benzene ring is attached to a three-carbon chain terminating in a chlorine atom with lone pairs (represented by ":Cl:"). Above the reaction arrow is "AlCl3". **Explanation:** The provided image showcases a typical Friedel-Crafts alkylation reaction. Benzene reacts with a halomethane in the presence of aluminum chloride (AlCl3) to form an alkylbenzene. The starting material is 1-chloro-2-phenylbutane. - **Reactants**: - Benzene ring attached to a three-carbon chain terminating with a chlorine atom at the end (1-chloro-2-phenylbutane). - AlCl3 (aluminum chloride). - **Expected Reaction Mechanism**: 1. The chlorine atom on the halomethane reacts with AlCl3 to generate a carbocation (a positively charged carbon species) and AlCl4^-. 2. The benzene ring then undergoes electrophilic aromatic substitution where it interacts with the carbocation, leading to the formation of an alkyl-substituted benzene. **Predicted Major Product:** The major product in this reaction will likely be 1-phenylbutane, where the carbocation (formed after the chlorine leaves the 1-chloro-2-phenylbutane) attaches itself to the benzene ring. However, rearrangements can occur depending on the stability of the carbocations formed during the reaction.
