Benzene reacts with n-propyl chloride in the presence of anhydrous AlCl3 to give:

1. 3-Propyl-1-chlorobenzene
2. n-Propylbenzene
3. No reaction
4. Isopropylbenzene

Correct answer: Isopropylbenzene

Solution

In the presence of anhydrous AlCl3, a Friedel-Crafts alkylation occurs. The n-propyl carbocation rearranges to a more stable isopropyl carbocation, leading to the formation of isopropylbenzene.
