Concept Introduction:
Valence Shell Electron Pair Repulsion Theory:
The shape or structure of a molecule is determined by the repulsion between the entire electrons present in the valence shell.
Bond pairs and lone pairs in the molecule repel each other therefore the electron clouds stay apart as possible to reduce the repulsion and so to increase the stability.
The amount of repulsion can be ordered as follows,
In order to determine the shape, the Lewis diagram must be drawn first.

- 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.
