Document Summary
Hydrogen bonds: unusually strong dipole-dipole interactions are observed among hydrogen-containing molecules in which hydrogen is covalently bonded to a highly electronegative element of small atomic size (fluorine, oxygen, nitrogen: fon, two factors. The highly electronegative element to which hydrogen is covenant bonded attracts the bonding electrons to such a degree that the hydrogen atom is left with a significant partial positive charge. The small size of the bare hydrogen nucleus allows it to approach closely, and be strongly attracted to a lone pair of electrons on the electronegative atom of another molecule. Solution: a homogeneous mixture of two or more substances with each substance retaining its own chemical activity, components of a solution. Solute - component of a solution that is present in lesser amount relative to that of the solvent; substance being dissolved. Solvent - component of a solution that is present in the greatest amount; liquid water.
