Question

Quizplus · Accepted Answer

The reaction involves a Friedel-Crafts acylation of benzene with acetyl chloride in the presence of AlCl3 catalyst. The major product formed will be the ortho-substituted product (III) due to the formation of a stable intermediate with the acylium ion. The para-substituted product (IV) may also be formed as a minor product. The meta-substituted product (I) and the product with a substitution at the acetyl group (II) are not expected to be formed. Therefore, the best choice is C, which corresponds to the major product (III).
