The reactions of (S)-5-methoxyhexan-3-one and 3,5-hexanedione lead to different products, which can be monitored by chiral and normal-phase HPLC. The goal is to identify the number of peaks in each type of HPLC, which reflects the complexity and stereochemical nature of the products. The correct answer indicates that there are 4 peaks in chiral HPLC and 3 peaks in normal-phase HPLC, suggesting a specific outcome in terms of product formation and stereochemistry."}
