WebJan 7, 2024 · The element argon (Ar) has eight valence electrons and is a liquid at very low temperatures. Sketch a model of two argon atoms and where each atom’s electrons need to be in order for an attractive dispersion force to occur. Make a similar sketch that explains why larger molecules typically experience larger dispersion forces. WebThe shapes of molecules also affect the magnitudes of the dispersion forces between them. For example, boiling points for the isomers n-pentane, isopentane, and neopentane (shown in the figure below) are 36 °C, 27 °C, and 9.5 °C, respectively.Even though these compounds are composed of molecules with the same chemical formula, C 5 H 12, the …
