The Irish culture uses the Claddagh symbol, the Celtic Knot and the Trinity Knot to express their love for one another. These symbols bring the Celtic people together as one. They are popularly used throughout jewelry, decorations and expressive art.
Because HCl is a polar molecule but doesn't have the H-F, H-O, or H-N bonds needed for hydrogen bonding, its intermolecular forces are dipole-dipole forces. This does not actually experience Hydrogen bonds as it is not Hydrogen bonded with either N,O, or F. London dispersion forces occur from the attraction between temporarily polarized nonpolar molecules. Here's what happens: The electrons in a molecule are pretty much randomly and evenly distributed.
As a result, the strongest type of intermolecular interaction between molecules of these substances is the London dispersion force . Due to the fact that the polar bonds do not cancel in the remaining molecules, they exhibit dipole - dipole interactions: these are stronger than London dispersion forces. However, #HF# exhibits hydrogen bonding - a stronger force still that is similar to the dipole - dipole interaction - whilst #CHF_3# does not. Thus, strength of intermolecular forces between molecules of each of these substances can be expressed, in terms of strength, as: #CF_4 = OF_2 < CHF_3 < HF#.
