Intermolecular Forces: Miscibility, Melting and Boiling Points

Witryna27 paź 2024 · The more compact shape of isopentane offers a smaller surface area available for intermolecular contact and, therefore, weaker dispersion forces. Neopentane molecules are the most compact of the three, offering the least available surface area for intermolecular contact and, hence, the weakest dispersion forces.
