Concept explainers
Interpretation:
Shape of an arsenic pentafluoride molecule has to be predicted.
Concept Introduction:
Valence shell electron pair repulsion theory or VSEPR model is used to determine geometry of molecules. This is done with help of number of electron pairs that are present around central atom. According to this model, electron groups are arranged in such manner that minimizes repulsion with other electrons.
In order to determine the shape, the steps to be followed are indicated as follows:
1. Lewis structure of molecule should be written.
2. The type electron arrangement around the central atom should be identified by means of table illustrated as follows:
3. Then bonded-atom unshared -pair arrangement that can maximize the distance of electron pairs about central atom determines the shape.
