Question

How does the VSPER theory explain molecular shape

A. Electron pair attractions pull atoms together
B. Electron pairs repelling each other push atoms apart
C. Valence electrons modify core electron orbitals
D. Intermolecular forces distort electron bonds

Answer 1

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.
