Quite often, the partial charges are not explicitly written when drawing hydrogen bonds, but they are always there.
Illustrated in theFigure9.21 are a few more examples of hydrogen bonding in molecules.

Lesson Summary
- A variety of interactions can occur between molecules that involve attractions between full or partial charges.
- Molecules that have a partial positive region and a partial negative region are said to possess a molecular
dipole. The interactions between these dipoles are what allow molecules to condense into the liquid or solid
states. - Even completely nonpolar molecules can attract each other due to dispersion forces.
- The hydrogen bond is a special type of dipole-dipole interaction that is seen in a variety of molecular com-
pounds.
