2
Intramolecular Forces
The attractive forces that hold particles together in ionic, covalent, and metallics bonds are called intramolecular forces.
3
Intermolecular Forces
Attractive forces between molecules cause some materials to be solids, some to be liquids, and some to be gases at the same temperature.

Intermolecular Forces cont.
Dispersion forces are weak forces that result from temporary shifts in density of electrons in electron clouds.

11
Intermolecular Forces cont.
Hydrogen bonds are special dipole-dipole attractions that occur between molecules that contain a hydrogen atom bonded to a small, highly electronegative atom with at least one lone pair of electrons, typically fluorine, oxygen, or nitrogen.

14
Intermolecular Forces cont.
Hydrogen bonds explain why water is a liquid at room temperature while compounds of comparable mass are gases.
Methane is nonpolar, so relatively weak dispersion forces holding the molecule together.
15
Intermolecular Forces cont.
Ammonia and Water both form hydrogen bonds but oxygen is more electronegative than nitrogen making O-H bonds more polar and thus stronger
