Between-molecule

The term 'between-molecule' describes the interactions, forces, or spaces that exist or occur *in the area of or acting upon the space between individual molecules*. It's a concept central to understanding a wide range of physical phenomena and chemical reactions. These interactions can include, but are not limited to, van der Waals forces (dispersion, dipole-dipole, dipole-induced dipole), hydrogen bonds, electrostatic interactions, and the physical space itself occupied by matter. Its study aids in the understanding of physical properties like boiling point, surface tension, and viscosity. The nature and strength of these interactions dictate the bulk behavior of matter, from the formation of solids and liquids to the rates of chemical reactions. This field includes studying the physical space that exists within a molecule for its interactions and reactions.

Between-molecule meaning with examples

• In water, the Between-molecule hydrogen bonds are responsible for its relatively high boiling point compared to similar-sized molecules. These strong attractions require more energy to overcome, impacting physical properties of the water. This interaction dictates the state of the water at a given temperature.
• The properties of a liquid crystal display (LCD) depend heavily on the precise Between-molecule interactions within the liquid crystal material. These forces allow the liquid crystals to align and reorient when an electric field is applied, this controls the way light passes through it, producing the visual image we see on display.
• The process of dissolution, such as salt dissolving in water, is significantly influenced by the Between-molecule forces between the solute (salt) and the solvent (water). These forces dictate the solubility of the salt in water, which determines the speed the molecules break apart and spread.
• Catalysis often involves manipulating the Between-molecule interactions between reactants and the catalyst, allowing the reaction to occur more efficiently. The catalyst provides a surface that allows the molecules to align and interact with each other, creating a chemical bond.
