1. Pick a molecule
Pick a molecule to start.
2. Is the molecule polar?
3. Strongest force
Pick a molecule, then choose polar or nonpolar and the strongest force.
Boiling points you have found
Boiling points at 1 atm, rounded (NIST Chemistry WebBook and CRC Handbook). Lower bars boil at lower temperatures.
Hints. Nonpolar: only dispersion. Polar: dipole-dipole. Hydrogen bonds need H bonded directly to N, O or F. Bigger molecules have stronger dispersion forces.
