2. It was suspected that a particular sample (mixture) contained three components: X, Y and Z. To check this, the sample was analyzed by thin layer chromatography. In this experiment a nonpolar solvent was used with a polar stationary phase. Before: O O X Y 2 sample After: O Y 2 sample Answer the following questions: Solvent front Line of origin a. Which suspected components (X, Y or Z) are present in the sample? b. Are there components other than X, Y or Z in the sample?

1. From spinach, the chromatographic analysis will yield two major substances: (a) B-carotene (C40H56), which will separate from the spinach mixture to form a yellow band, and (b) chlorophyll A (CSSH72MGN4OS), which will separate from the mixture to form a green band. i. Describe the characteristics and draw structures of these molecules. ii. From the spectrophotometric analysis, what wavelength (Amax) would you expect ß-carotene (C40H56) to absorb? What wavelength would chlorophyll A (CssH72MgN4O5) absorb?
