(a)
Interpretation:
Most polar phase should be identified from mobile phase and stationary phase in reverse phase column chromatography.
Concept Introduction :
Column chromatography is a large scale solid-liquid adsorption chromatographic technique that can separate multi-gram amounts of mixtures. This is a preparative version of thin layer chromatography that permits separation and isolation of products by collection of eluted fractions.
There are two types of column chromatography named as normal phase-column chromatography and reverse − phase column chromatography.
(b)
Interpretation:
Reverse-phase chromatography is more appropriate in separating peptides than normal-phase chromatography should be explained.

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.
