A partly electrostatic, partly covalent interaction between a donor group such as O--H or N--H and an electronegative acceptor atom such as O or N.
Occur between particles that are polar but not actually charges
Van der Waal's radius
The distance from an atom's nucleus to its effective electronic surface.
Van der Waal's interaction
A weak noncovalent association between molecules that arises from the attractive forces between polar groups (dipole-dipole interaction) or between nonpolar groups whose fluctuating electron distribution gives rise to temporary dipoles (London dispersion forces).
A measure of an atom's affinity for electrons.
A type of van der Waals interaction between two strongly polar groups.
London dispersion forces
The weak van der Waals interactions between nonpolar groups as a result of fluctuations in their electron distributions that create a temporary separation of charge (polarity).
Having high enough polarity to readily interact with water molecules. Hydrophilic substances tend to dissolve in water.
Having insufficient polarity to readily interact with water molecules. Hydrophobic substances tend to be insoluble in water.
The tendency of water to minimize its contacts with nonpolar substances, thereby inducing the substances to aggregrate
(Amphipathic) Having both polar and non-polar regions and therefore being both hydrophilic and hydrophobic.
Having both polar and non-polar regions and therefore being both hydrophilic and hydrophobic (amphiphilic)
A globular aggregate of amphiphilic molecules in aqueous solution that are oriented such that polar segments form the surface of the aggregate and the non-polar segments form a core that is out of contact with the solvent.
