What is the major organic product obtained in the following reaction?

Question

Quizplus · Accepted Answer

The reaction is a Friedel-Crafts acylation reaction, where acetyl chloride reacts with benzene in the presence of aluminum chloride as a catalyst. The major organic product obtained is IV, which is acetophenone. This is because the acetyl group is a good electrophile and is easily added to the benzene ring, forming a carbocation intermediate. The intermediate then undergoes deprotonation to give the final product, acetophenone. The other choices are minor products, with I being a side product due to over-alkylation, II being a side product due to Friedel-Crafts alkylation, and III being a side product due to acylation at the ortho position.
