4.2 Molecular Geometry and Polarity

Front

What is molecular geometry?

Back

Molecular geometry refers to the three-dimensional arrangement of atoms within a molecule, which influences its physical and chemical properties.

Front

Define polarity in molecules.

Back

Polarity in molecules refers to the distribution of electrical charge over the atoms in a molecule, leading to regions of partial positive and negative charge.

Front

What is the VSEPR theory?

Back

The Valence Shell Electron Pair Repulsion (VSEPR) theory predicts the shape of molecules based on the repulsion between electron pairs in the valence shell of the central atom.
