Question

which molecule should have the lowest volatility? (dispersion forces, dipole-dipole) (dispersion forces) (dispersion forces, dipole-dipole, hydrogen bonding) n₂ ch₃cl nh₃ all three molecules have the same volatility.

Explanation:

Volatility is inversely related to intermolecular force strength. Stronger forces mean lower volatility. $\text{NH}_3$ has hydrogen bonding (strongest), $\text{CH}_3\text{Cl}$ has dipole-dipole, and $\text{N}_2$ has only dispersion forces. Thus, $\text{NH}_3$ has the lowest volatility.

Answer:

NH₃
