Substances x and y are both nonpolar. if the volatility of x is higher than that of y, what is the best explanation? x’s molecules experience stronger dipole-dipole forces than y’s molecules. y’s molecules experience stronger dipole-dipole forces than x’s molecules. x’s molecules experience stronger london dispersion forces than y’s molecules. y’s molecules experience stronger london dispersion forces than x’s molecules.

Answer is: Y’s molecules experience stronger London dispersion forces than X’s molecules.

Volatile means evaporating or vaporizing readily under normal conditions.

The London dispersion force (intermolecular force) is a temporary attractive force between nonpolar molecules.

Intermolecular forces are the forces between molecules. The stronger are intermolecular forces, the lower is the volatility.

Y’s molecules experience stronger London dispersion forces than X’s molecules.
