🧠 The "Sticky" Gas Rule
Liquefaction is the process of forcing molecules to stick together and stay together. A gas that is "naturally sticky" (high intermolecular attraction) is far easier to liquefy than a "lonely" gas.

🗺️ The Constant 'a' Logic
1. The Meaning: The Van der Waals constant 'a' is a direct measurement of the intermolecular forces between gas molecules.
2. The Comparison:

3. The Conclusion: Ammonia () has the largest 'a' value due to its polar nature an
