The major attractive force for hydrocarbons should be the London forces, which scale with … WebSep 6, 2024 · Branching decreases the boiling point So the increase of surface area increases the ability of individual molecules to attract each other. Branching in molecules decreases the surface area thereby decreasing the attractive force between individual molecules. As a result, the boiling point decreases. Does acidity affect boiling point? tspsc online courseWebFeb 19, 2024 · Answer. 4 people found it helpful. penu2008. Branching decreases the boiling point. As the length of carbon chain increases, the surface area of the compound will also increase. Van der Waals dispersion force is proportional to the surface area. So the increase of surface area increases the ability of individual molecules to attract each other. tsps conference

"WebJul 7, 2024 · What effect does branching of alkane have on boiling point? As branches increases, the surface area of molecule decreases resulting in a small area of contact. As a result, the Van der Waals force also decreases which can overcome at a relatively lower temperature. Hence, the boiling point of an alkane chain decreases with an increase in … " - How does surface area affect boiling point

Boiling Point And Surface Area: Detailed Facts

WebOctane will have a higher boiling point than 2,2,3,3‑tetramethylbutane, because it branches less than 2,2,3,3‑tetramethylbutane, and therefore has a larger “surface area” and more van der Waals forces. Note: The actual boiling points are nonane, 150.8°C octane, 125.7°C 2,2,3,3‑tetramethylbutane, 106.5°C Contributors and Attributions WebThe shape of a molecule can also affect the boiling point. Typically, molecules with a smaller surface area have weaker London forces and result in lower boiling point.

WebApr 16, 2024 · Increasing the contract surface area between hydrocarbons raises boiling point, so hexane should have a higher boiling point than propane. This doesn't really make sense to me. What is the difference between pulling apart a pair of propane twice, versus one pair of hexane? Why would the total amount of energy needed differ? WebFeb 20, 2011 · Boiling point elevation is the raising of a solvent's boiling point due to the addition of a solute. Similarly, freezing point depression is the lowering of a solvent's freezing point due to the …

Web1. number of carbons (increase in number of carbons, and hence molecular weight, increases BP) 2. Like you said, surface area. (increase in SA results increase in BP) 3. The strength of IMF. So I believe, that because nonane has more number of carbons AND more surface area, that's TWO factors that makes it have higher BP. WebSep 14, 2015 · At another extreme, in Death Valley, Calif. – the lowest point in the U.S., at 282 feet below sea level – water boils at slightly above 212 degrees.
