EXAMPLE - Among … WebApr 9, 2024 · As the branching is done in a molecule or the branches increase the surface area of the molecule decreases which results in the decrease of van der waals attraction. Due to decrease in attraction it becomes easier to overcome a molecule, at low temperature we can overcome it, hence the boiling point of an alkane decreases on branching.

How Does Branching Affect Boiling Point And Melting?

WebWhat is the effect of branching of alkane on its boiling point? As branching increases, the surface area of the molecule decreases which results in a small area of contact. As a result, the Van der Waals force also decreases which can be overcome at a … WebMay 31, 2014 · The strength of Van der Waals forces depends primarily on the number of electrons in total in the molecule, so larger molecules will have higher boiling points. For isoelectonic molecules (isomers with the same number of electrons) what determines the strength of the Van der Waals forces is the area of surface contact. dia of 10-32

Understanding How Intermolecular Forces Affect Boiling …

WebFeb 20, 2016 · When a liquid evaporates in the open, the condensation rate is negligible. Increasing the surface area increases the evaporation rate, but it has little effect on the condensation rate. Hence, water in an open dish evaporates faster than water in a test tube, but the vapour pressure does not change. Answer link 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. dia of 10 gauge wireWebJul 21, 2024 · An increase in the surface area facilitates evaporation of the sweat by absorption of heat equal to the latent heat of vaporization from the body and the cotton clothes. As a result, our body feels cool & comfortable. Similarly, when we take ice-cold water in a glass tumbler, we see water droplets on the outer surface of the glass. citibank foster city ca

"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? " - How does surface area affect boiling point
