Intermolecular vs. Intramolecular Forces
This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.
State
Intramolecular forces hold one molecule's own atoms together; intermolecular forces are the weaker attractions between neighboring molecules.
Show
Boiling one mole of liquid HCl needs about 17 kilojoules; breaking its H-Cl bond needs about 430 kilojoules instead.
Watch for
"Intra-" and "inter-" differ by one prefix but describe forces roughly twenty-five times apart in strength.
