According to Valence Shell Electron Pair Repulsion (VSEPR) theory, what does the theory primarily predict for molecules?

• A. The color of compounds in solution
• B. The type of chemical bonds formed between atoms
• C. The rate at which chemical reactions occur
• D. The three-dimensional shape or geometry of molecules based on electron pair repulsion

Answer: (D)

Verified step by step guidance

1. Understand that Valence Shell Electron Pair Repulsion (VSEPR) theory is a model used to predict the shape of molecules.
2. Recall that VSEPR theory is based on the idea that electron pairs around a central atom repel each other and will arrange themselves as far apart as possible to minimize repulsion.
3. Recognize that this repulsion affects the three-dimensional geometry of the molecule, determining bond angles and molecular shape.
4. Note that VSEPR theory does not predict properties like color, bond types, or reaction rates; it specifically focuses on molecular geometry.
5. Conclude that the primary prediction of VSEPR theory is the three-dimensional shape or geometry of molecules based on electron pair repulsion.
