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.
Thus, they are called intermolecular forces. There are three main types of secondary bonds: dipole-dipole, London dispersion and hydrogen bonds. Hydrogen bond is a special type of dipole-dipole attraction that occurs between a lone pair of electrons on an electronegative atom and a hydrogen atom in a polar bond. The main difference between dipole-dipole and London dispersion forces is that dipole-dipole forces occur among molecules with dipole moment whereas London dispersions occur due to instantaneous dipoles that form in atoms or nonpolar molecules.
