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