The strongest attraction between molecules
Use this for “Which liquid evaporates faster, and which has the higher boiling point?”
Sort
What is the strongest attraction between these molecules?
Tap a card, then tap its group.
Assumptions
•
Every molecule has London dispersion forces; polar ones add dipole–dipole attractions.
•
Hydrogen bonding needs H bonded to N, O or F.
•
Stronger attractions mean a higher boiling point and slower evaporation.
