Polar molecules attract one another by dipole-dipole forces, as the positive end of one molecule is attracted to the negative end of the nearby molecule. In the case of water, the highly polar \(\ce{O-H}\) bonds results in very little electron density around the hydrogen atoms.

Cohesion is intermolecular forces between like molecules; this is why water molecules are able to hold themselves together in a drop. Water molecules are very cohesive because of the molecule's polarity. This is why you can fill a glass of water just barely above the rim without it spilling.
Figure \(\PageIndex{2}\): Water is a polar molecule, as greater electron density is found around the more electronegative oxygen atom. Polar molecules attract one another by dipole-dipole forces, as the positive end of one molecule is attracted to the negative end of the nearby molecule.
21 paź 2020 · Water is a polar molecule because of its bent geometry and the electronegativity difference between the hydrogen and oxygen atoms. The geometry, in turn, is due to oxygen’s two lone pairs. Water (H 2 O) is a polar molecule and a polar solvent.
Learning Objectives. By the end of this section, you will be able to: Predict the structures of small molecules using valence shell electron pair repulsion (VSEPR) theory. Explain the concepts of polar covalent bonds and molecular polarity. Assess the polarity of a molecule based on its bonding and structure.
The water molecule, visualized three different ways: ball-and-stick model, space-filling model, and structural formula with partial charges. The bent shape of the water molecule is critical because the polar O-H bonds do not cancel one another and the molecule as a whole is polar.
25 kwi 2001 · Many of water's basic physical properties can now be explained, at least semiquantitatively, in molecular and structural terms, although in spite of intense study it remains incompletely...
