What does VSEPR stand for?

• A. Valence Shell Electron Pair Repulsion
• B. Valence Shell Electron Pair Rotation
• C. Vacant Shell Electron Pair Repulsion
• D. Valence Shell Energy Pair Repulsion

Answer: (A)

The main idea is that VSEPR describes how electron pairs around a central atom arrange themselves to minimize repulsion. The acronym stands for Valence Shell Electron Pair Repulsion: “Valence” refers to the valence electrons involved in bonding, “Shell” means the electron orbitals around the atom, and “Electron Pair Repulsion” captures the key rule—pairs of electrons (both bonding and lone pairs) push away from each other, leading to particular molecular geometries. The other options use terms that don’t fit this idea (rotation instead of repulsion, vacant shell instead of valence shell, and energy pair instead of electron pair), so they don’t describe the concept correctly.
