Interpretation:
In the preparation of a TLC plate for the development, the result of making large spots needs to be explained.
Concept Introduction:
Chromatography is the best method of separation of components from the mixture as it gives most accurate results compare to other methods. In this method the mixture must be dissolved in certain fluid that is called as mobile phase. This mobile phase carries different components of mixture on the structure holding another material. This material is known as stationary phase. There are various types of chromatography methods such as column chromatography, thin layer chromatography, gas chromatography etc.
Answer to Problem 1Q
The large spot concludes that a lot of sample moves up in the plate that makes difficult to analyze the separation.
Explanation of Solution
In TLC technique or Thin layer chromatography, the solvent is used to separate the components of a mixture. The polarity of solvent plays an important role here. If the solvent has high polarity, all components will move along with it and cause large spot with no separation. Similarly if the solvent has low polarity, the components of mixture will not move that causes incomplete separation of them.
Hence large spot concludes that a lot of sample moves up in the plate that makes difficult to analyze the separation.
Thus, the large spot concludes that a lot of sample moves up in the plate that makes difficult to analyze the separation.

- b) Certain cyclic compounds are known to be conformationally similar to carbohydrates, although they are not themselves carbohydrates. One example is Compound C shown below, which could be imagined as adopting four possible conformations. In reality, however, only one of these is particularly stable. Circle the conformation you expect to be the most stable, and provide an explanation to justify your choice. For your explanation to be both convincing and correct, it must contain not only words, but also "cartoon" orbital drawings contrasting the four structures.
