Answer:
B. Electron pairs repelling each other push atoms apart
Step-by-step explanation:
The VESPR theory explains molecular shape by suggesting that electron pairs repelling each other push atoms apart.
If an atom is bonded to two or more other kinds of atoms as in many covalent molecules and ions, the shape of the system is determined by the geometry of the bonds around the central atom.
- The variations in the bond angles of such molecules is explained by the valence shell electron pair repulsion theory.
- All the electrons will orient themselves in such a way to minimize the electrostatic repulsion between them.
- The repulsions determines the geometry of the covalent bonds around the central atom.
