molar mass and attractive interactions

[Abigail Menchaca_1H]

Why does the increase in molar mass lead to stronger attractive interactions?

[Myka G 1l]

The larger a molecule is, the more electrons it has to participate in induced dipoles and also has a greater surface area for these interactions to occur.

[John Arambulo 1I]

An increase in size and molar mass means that there is more surface area for the atoms/molecules to have London dispersion forces. Although instantaneous and short-lived, the interaction is stronger with larger atoms and molecules because there are more electron distortion and polarizability of of electrons which would make more attractive fluctuating dipoles.

[Kimberly Koo 2I]

When molecules are larger and have a higher molar mass, then they have more electrons, which means that they have more attractive interactions.
