The reaction involves nucleophilic substitution, and the presence of the deuterium label on the aromatic ring can lead to different substitution patterns. The goal is to determine how many distinct organic products can be formed from this reaction. Analyzing the possible substitution sites on the aromatic ring will help in identifying the number of products."}
