Witryna12 lut 2024 · $\begingroup$ Your rule of thumb that the smallest (lowest MW) alkane will have the lowest BP and the largest (highest MW) will have the largest is just wrong. It works in this case because the molecules are all very small, "essentially" linear. Branching in higher weight alkanes makes it impossible to predict BP solely on the … WitrynaWhen comparing the structural isomers of pentane (pentane, isopentane, and neopentane), they all have the same molecular formula C 5 H 12. However, as the … Witryna13 lut 2024 · Neopentane is almost spherical, with a small surface area for intermolecular interactions, whereas n -pentane has an extended conformation that enables it to come into close contact with other n -pentane molecules. As a result, the boiling point of neopentane (9.5°C) is more than 25°C lower than the boiling point of n -pentane … raw and tires
