The chair conformation of α-form of disaccharide in which two units of D-glucopyranose joined by β-1,3-glycosidic bond has to be drawn. Concept Introduction: A disaccharide is said to be the carbohydrate molecule which contains two monosaccharide units linked by a glycosidic bond. The bond forms in between the anomeric carbon of one monosaccharide and the –OH group of another monosaccharide.

Question

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.
