Hydrogen Bonding Forces
bonding force is a specialized electrostatic force that is usually created by the
electrical attraction between the hydrogen of one molecule with the
oxygen of another. When the single electron orbiting a hydrogen atom is pulled
away by another atom in a molecule, a strong electromagnetic
attraction is created by the exposed hydrogen proton. The
hydrogen bonding force of a solvent increases as the number of exposed
hydrogen atoms in a molecule increases.
properties of solvents vary because the strength and the nature of the
component forces binding them together vary. In order to predict
whether a solvent will be able to dissolve a solute it is necessary to
determine the cumulative effect of the component forces that make up the
van der Waals force for that solvent. Click "Activity"
