Shape of Molecules and Strength of Interaction

Postby Danieljm1B » Sun Jul 21, 2019 9:09 pm

How does the shape of a molecule help to determine the strength of the interaction? I know that two examples were given in lecture having to do with rod-shaped and spherical molecules. However, I want to get further information as to how one has a stronger force than the other.

The intermolecular forces of attraction (like London dispersion forces) between spherical shaped molecules is less because of smaller surface area which makes it weaker and more reactive as compared to the rod-shaped one which has a larger surface area, thus having a stronger intermolecular force between molecules of the same kind.
