  2. Intermolecular force - Wikipedia

    en.wikipedia.org/wiki/Intermolecular_force

    Intermolecular forces observed between atoms and molecules can be described phenomenologically as occurring between permanent and instantaneous dipoles, as outlined above. Alternatively, one may seek a fundamental, unifying theory that is able to explain the various types of interactions such as hydrogen bonding , [ 22 ] van der Waals force ...

  3. Nitrogen trifluoride - Wikipedia

    en.wikipedia.org/wiki/Nitrogen_trifluoride

    By contrast, ammonia is basic and highly polar (1.47 D). [12] This contrast reflects the differing electronegativities of H vs F. Similar to dioxygen, NF 3 is a potent yet sluggish oxidizer. [6] It oxidizes hydrogen chloride to chlorine: [citation needed] 2 NF 3 + 6 HCl → 6 HF + N 2 + 3 Cl 2

  4. Chemical polarity - Wikipedia

    en.wikipedia.org/wiki/Chemical_polarity

    Polar molecules must contain one or more polar bonds due to a difference in electronegativity between the bonded atoms. Molecules containing polar bonds have no molecular polarity if the bond dipoles cancel each other out by symmetry. Polar molecules interact through dipole-dipole intermolecular forces and hydrogen bonds.

  5. London dispersion force - Wikipedia

    en.wikipedia.org/wiki/London_dispersion_force

    Interaction energy of an argon dimer.The long-range section is due to London dispersion forces. London dispersion forces (LDF, also known as dispersion forces, London forces, instantaneous dipole–induced dipole forces, fluctuating induced dipole bonds [1] or loosely as van der Waals forces) are a type of intermolecular force acting between atoms and molecules that are normally electrically ...

  6. Van der Waals force - Wikipedia

    en.wikipedia.org/wiki/Van_der_Waals_force

    In molecular physics and chemistry, the van der Waals force (sometimes van der 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] they are comparatively weak and therefore more susceptible to disturbance. The van der ...

  7. Non-covalent interaction - Wikipedia

    en.wikipedia.org/wiki/Non-covalent_interaction

    A dipole-induced dipole interaction (Debye force) is due to the approach of a molecule with a permanent dipole to another non-polar molecule with no permanent dipole. This approach causes the electrons of the non-polar molecule to be polarized toward or away from the dipole (or "induce" a dipole) of the approaching molecule. [13]

  8. Hansen solubility parameter - Wikipedia

    The energy from dipolar intermolecular forces between molecules δ h {\displaystyle \ \delta _{h}} The energy from hydrogen bonds between molecules. These three parameters can be treated as co-ordinates for a point in three dimensions also known as the Hansen space.
