Question

In the final product, triphenylmethyl ethyl ether, there is only one oxygen atom. From which of the two starting materials did it come?

**Prelab Questions:** 1. In the final product, triphenylmethyl ethyl ether, there is only one oxygen atom. From which of the two starting materials did it come? 2. Calculate the \( R_f \) value for the spot on the TLC plate shown below. Measure distances in mm (with a ruler) and show your work. ![TLC plate diagram](<URL Placeholder>) - **Explanation:** The diagram shows a vertical rectangle representing a TLC plate. There is a dot indicating the origin where the sample was applied at the bottom. There is a spot further up the plate representing the position to which the compound has traveled. A dashed line at the top indicates the solvent front. 3. Would you expect an alcohol or an ether to have a higher \( R_f \) value on silica gel thin layer chromatography? Why?
