While there is no net charge to a water molecule, the polarity of water creates a slightly positive charge on hydrogen and a slightly negative charge on oxygen, contributing to water’s properties of attraction. Water’s charges are generated because oxygen is more electronegative, or electron loving, than hydrogen.
16 Απρ 2023 · Because water is polar, substances that are polar or ionic will dissolve in it. Because of the shape of the molecule and the polar —OH grouping in methanol, we expect its molecules to be polar and for it to be soluble in water.
Read this tutorial to know why water is polar! We will provide you with the basics of polarity, as well as what polarity means for water (e.g. H-bonding, surface tension, and more)!
polarity, in chemical bonding, the distribution of electrical charge over the atoms joined by the bond. Specifically, while bonds between identical atoms, as in H 2, are electrically uniform in the sense that both hydrogen atoms are electrically neutral, bonds between atoms of different elements are electrically inequivalent.
Water’s polarity makes it a very good polar solvent for many biological molecules. For example, in ionic calcium chloride, the positive Ca2+ will be attracted to the negative pole of a water molecule, and Cl- will be attracted to the positive pole.
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.
While there is no net charge to a water molecule, the polarity of water creates a slightly positive charge on hydrogen and a slightly negative charge on oxygen, contributing to water’s properties of attraction.
