Which statement is true regarding larger molecules and London dispersion forces?

Larger molecules have stronger London dispersion forces due to their increased number of electrons and larger surface area, which enhance the ability of temporary dipoles to form. London dispersion forces, also known as van der Waals forces, arise from the momentary distribution of electrons within molecules, leading to transient induced dipoles. As a molecule becomes larger and more complex, it typically has more electrons. This increase in electron count enhances the polarizability of the molecule, meaning that its electron cloud can be distorted more easily, resulting in stronger interactions with neighboring molecules.

Additionally, the larger surface area of bigger molecules allows for more points of contact, further contributing to the strength of London dispersion forces. As a result, boiling points generally increase for larger molecules due to the greater energy required to overcome these stronger intermolecular forces, making the statement that larger molecules have stronger London dispersion forces accurate.
