Water is a polar molecule, meaning that there is an uneven distribution of electron density. Water has a partial negative charge () near the oxygen atom due the unshared pairs of electrons, and partial positive charges () near the hydrogen atoms.
In general, each nonbonding pair, single bond, or multiple bond produces an electron domain around the central atom. Because electron domains are negatively charged, they repel one another. The best arrangement of a given number of electron domains is the one that minimizes the repulsion between them.n general, electron domains for multiple bonds exert a greater repulsive force on adjacent electron domains than do electron domains for single bonds. In contrast, the molecular geometry is the arrangement of only the atoms in a molecule or ion (non-bonding pairs are not part of molecular geometry).
