Question

**Exercise 6: Analyzing Separation Effectiveness with Column Chromatography**

In this exercise, you are tasked with separating two compounds using column chromatography. Upon running the column, you collect the eluent in five fractions. To evaluate the efficiency of your separation process, you analyze each fraction using Thin Layer Chromatography (TLC), as depicted in the diagram below.

**TLC Plate Analysis:**

The TLC plate consists of five lanes, each corresponding to a fraction obtained from the column chromatography:

- **Lane 1:** Displays two distinct spots, indicating the presence of two compounds, suggesting incomplete separation.
- **Lane 2:** Shows a single spot, likely one of the separated compounds.
- **Lane 3:** Also displays a single spot, presumed to be the other compound.
- **Lane 4:** Shows two spots, similar to Lane 1, indicating partial separation.
- **Lane 5:** Displays two distinct spots, again suggesting incomplete separation.

**Conclusion:**

The TLC plate reveals that the separation of the two compounds was partially effective. Fractions 2 and 3 each contain only one compound, indicating some degree of success in separating them. However, the presence of two spots in fractions 1, 4, and 5 suggests that further optimization of the chromatography process is needed to achieve complete separation.

A standard sample of compound A was placed on a silica TLC plate. After elution in 30/70 ethyl acetate/hexane, the sample showed a single spot at 3.4 cm (relative to the initial point) after the solvent had risen to 7.1 cm (relative to the initial point). A sample which was thought to contain this compound was analyzed by TLC and showed two spots after elution in the same solvent system. The solvent height for this plate was 6.5 cm (relative to the initial point) and the spots were located at 3.6 cm and 5.2 cm (relative to the initial point). Can either of these spots possibly be compound A? Explain. Include a discussion of the R, for each spot.
