The relationship between molecular weight, intermolecular forces, and volatility is a fundamental thermodynamic principle of physical chemistry that requires no specific citation.
The claim states that molecular weight and intermolecular forces determine chemical volatility, which is a well-established and universally accepted fundamental principle of chemistry. By definition, heavier molecules with stronger intermolecular attractions (such as hydrogen bonding) require more energy to vaporize, lowering their volatility. This makes the statement a matter of basic scientific fact and common knowledge, so no papers are assigned.
