Use the following scenario and results to answer the following four questions: Scenario:  It was suspected that a particular drug sample contained three components: X, Y and Z. To check this, the mixture was analyzed by TLC with a nonpolar developing solvent on silica gel. The following TLC plate was obtained. Which components are most likely to be present in the sample?     X and Z     Y only     Y and Z     Y and another unknown component     X and Y

### Paper Chromatography Experiment Illustration #### Diagram Description: The diagram consists of two panels labeled "before" and "after," each representing a stage in a paper chromatography process. - **Before Panel:** - Shows a horizontal baseline at the bottom of the paper labeled "origin line." - Four dots aligned along this line are labeled X, Y, Z, and "sample" representing different substances or mixtures that are to be separated. - **After Panel:** - Includes the same vertical scale marked in centimeters from 0 to 6 cm, with 0 being at the origin line. - The "solvent front" is drawn at the 6 cm mark, representing the furthest point the solvent has traveled. - Dots corresponding to the substances have moved upwards to different heights: - X has traveled to approximately 3 cm. - Y has traveled to approximately 4.5 cm. - Z has traveled to about 2.5 cm. - "Sample" shows multiple spots, indicating it is a mixture. ### Explanation: This diagram illustrates how paper chromatography is used to separate substances in a mixture. Each substance travels a different distance based on its affinity for the solvent versus the stationary phase of the paper. The positions of the spots after the process indicate the relative solubilities.
