Hypothesis: State your prediction for the ranking based on your prior knowledge of molecular structure (e.g., "We hypothesize the ranking from weakest to strongest IMFs will be: Hexane, Acetone, IPA, Water, because...").

We hypothesize the ranking from weakest to strongest intermolecular forces (IMFs) will be:
Hexane < Acetone < Isopropyl alcohol (IPA) < Water.

Why:
- Hexane: nonpolar hydrocarbon — only London dispersion forces, so weakest IMFs.
- Acetone: polar aprotic — has dipole–dipole interactions plus dispersion, stronger than hexane.
- Isopropyl alcohol: polar protic — can hydrogen-bond (both donor and acceptor) in addition to dipole and dispersion, so stronger than acetone.
- Water: small, highly polar, and forms an extensive hydrogen‑bonding network (each molecule can form multiple H‑bonds) — strongest IMFs of the group.

If you want, I can convert this into a testable prediction (e.g., expected boiling points or solubilities) or adapt the hypothesis for a different set of molecules.
