The first reaction involves the reduction of a chiral compound, which can yield multiple peaks due to the presence of enantiomers. The second reaction involves a diketone that can also produce distinct products. The goal is to identify the number of peaks observed in both chiral and normal-phase HPLC chromatograms, leading to the conclusion that there are 5 peaks in chiral HPLC and 4 peaks in normal-phase HPLC."}
