Even non-polar molecules stick

An interactive lesson with 7 steps, about 6 minutes: you predict, drag and solve, with instant feedback on every answer. It runs in your browser and needs JavaScript.

What you’ll learn

• Dispersion forces come from fleeting dipoles and act between all molecules.
• Bigger molecules and longer, straighter shapes → stronger dispersion → higher boiling point.

Steps

1. Flickering dipoles
2. Clouds that flicker together
3. Read the trend
4. Branches
5. Halogens
6. Geckos
7. Predict nonane
