Molecular geometry describes the 3D arrangement of atoms in a molecule. It is determined by electron pair repulsion (VSEPR theory) and the number of bonding and lone pairs on the central atom. Geometries range from linear (CO2) to tetrahedral (CH4) to more complex shapes like seesaw or T-shaped. Molecular geometry affects properties such as polarity, reactivity, and intermolecular forces, critically impacting how molecules interact in chemical and biological systems.
