  2. Chemical polarity - Wikipedia

    en.wikipedia.org/wiki/Chemical_polarity

    Chemical polarity. A water molecule, a commonly used example of polarity. Two charges are present with a negative charge in the middle (red shade), and a positive charge at the ends (blue shade). In chemistry, polarity is a separation of electric charge leading to a molecule or its chemical groups having an electric dipole moment, with a ...

  3. Covalent bond - Wikipedia

    en.wikipedia.org/wiki/Covalent_bond

    Covalent bonds are also affected by the electronegativity of the connected atoms which determines the chemical polarity of the bond. Two atoms with equal electronegativity will make nonpolar covalent bonds such as H–H. An unequal relationship creates a polar covalent bond such as with H−Cl.

  4. Carbon–hydrogen bond - Wikipedia

    en.wikipedia.org/wiki/Carbon–hydrogen_bond

    Carbon–hydrogen bond. In chemistry, the carbon–hydrogen bond (C−H bond) is a chemical bond between carbon and hydrogen atoms that can be found in many organic compounds. [1] This bond is a covalent, single bond, meaning that carbon shares its outer valence electrons with up to four hydrogens. This completes both of their outer shells ...

  5. Chemical bond - Wikipedia

    en.wikipedia.org/wiki/Chemical_bond

    Molecules that are formed primarily from non-polar covalent bonds are often immiscible in water or other polar solvents, but much more soluble in non-polar solvents such as hexane. A polar covalent bond is a covalent bond with a significant ionic character. This means that the two shared electrons are closer to one of the atoms than the other ...

  6. Non-covalent interaction - Wikipedia

    en.wikipedia.org/wiki/Non-covalent_interaction

    Non-covalent interaction. In chemistry, a non-covalent interaction differs from a covalent bond in that it does not involve the sharing of electrons, [1] but rather involves more dispersed variations of electromagnetic interactions between molecules or within a molecule. The chemical energy released in the formation of non-covalent interactions ...

  7. Hydrophobe - Wikipedia

    en.wikipedia.org/wiki/Hydrophobe

    Water drops on the hydrophobic surface of grass. In chemistry, hydrophobicity is the chemical property of a molecule that is seemingly repelled from a mass of water (called a hydrophobe). [1] In contrast, hydrophiles are attracted to water. Hydrophobic molecules tend to be nonpolar and, thus, prefer other neutral molecules and nonpolar solvents.

  8. Van der Waals force - Wikipedia

    en.wikipedia.org/wiki/Van_der_Waals_force

    Microfiber cloth makes use of van der Waal' s force to remove dirt without scratches. [1] In molecular physics and chemistry, the van der Waals force (sometimes van de Waals' force) is a distance-dependent interaction between atoms or molecules. Unlike ionic or covalent bonds, these attractions do not result from a chemical electronic bond; [2 ...

  9. Iodine monochloride - Wikipedia

    en.wikipedia.org/wiki/Iodine_monochloride

    Iodine monochloride is an interhalogen compound with the formula ICl. It is a red-brown chemical compound that melts near room temperature. Because of the difference in the electronegativity of iodine and chlorine, this molecule is highly polar and behaves as a source of I +.
