(a)
Interpretation:
The expected shape for the given anion has to be determined.
Concept introduction:
VSEPR model:
- Valance Shell Electron-Pair Repulsion (VSEPR) model is used to predict the shapes of the molecules by the electronic structure of its atoms.
- Electrons that are involved in bonds and in lone pairs of electrons should be thought like occupying “charge clouds” or regions of electron density.
- These region of electron density can repel one another and stay as much as possible and results to assume specific shapes.
Rules to predict the shapes of molecules by VSEPR model:
- Write electron-dot structure of the given molecule.
- Count the number of electron charge clouds surrounding the central atom.
- Determine the geometric arrangement of charge clouds surround the each atom and assume its charge clouds can be oriented in the space as far away from one to another as possible.
