How does the size of a nonpolar molecule generally influence the strength of its London Dispersion Forces (LDFs)?

Answer

Larger molecules have more electrons, leading to more polarizable electron clouds and stronger LDFs.

Larger molecules possess larger electron clouds, making them more polarizable—meaning their electron distribution is more easily distorted—which results in stronger transient dipoles and thus stronger London dispersion forces.
