As a chemistry expert with a deep understanding of molecular structures and their properties, I am well-equipped to discuss the polarity of molecules, such as H2O, commonly known as water. Polarity in a molecule is determined by the distribution of electron density across the molecule. A polar molecule has a separation of charge, with one end being more electronegative and the other end more electropositive.
In the case of water, the molecule is composed of two hydrogen atoms and one oxygen atom, with the oxygen atom being the central atom in a bent or V-shaped molecular geometry. Oxygen is more electronegative than hydrogen, which means it has a greater tendency to attract electrons towards itself. This results in a polar covalent bond where the shared electrons are more attracted to the oxygen atom, creating a partial negative charge on the oxygen and a partial positive charge on the hydrogen atoms.
The molecular geometry of water further contributes to its polarity. Due to the bent shape, the dipole moments of the O-H bonds do not cancel each other out. Instead, they add up, resulting in an overall molecular dipole moment. This gives water its characteristic polar nature, with the oxygen end of the molecule being more negative and the hydrogen ends being more positive.
This polarity is the reason why water is a universal solvent. The partial charges allow water molecules to interact with a wide variety of substances through hydrogen bonding and dipole-dipole interactions. The polarity of water also plays a crucial role in many of its physical properties, such as its high boiling point, high heat capacity, and its ability to form a liquid structure that supports life.
In summary, the polarity of water is a fundamental aspect of its chemical behavior and is essential for understanding its role in biological systems and as a solvent in chemistry. The electronegativity difference between oxygen and hydrogen, combined with the bent molecular geometry, results in a polar molecule with distinct regions of partial positive and negative charge.

The Nitrogen atom is more electronegative and therefore the valence electrons are near them more often. This makes it more negative. The Hydrogen atoms at the bottom of the structure are then more positive. Therefore, H2O is a polar molecule.Aug 5, 2013
