WebFeb 15, 2024 · The alkane will have greater dispersion forces because for the same carbon length (e.g. comparing hexane to hexene), the alkane will have more electrons and a greater area over which to spread those electrons. This will increase the dispersion force and so we would expect the alkane to have a slightly higher boiling point than the alkene with ... WebJun 1, 2024 · The term "Van der Waals forces" was used by (at least) ... An alkene has 2 less electrons than the respective/corresponding alkane, therefore the boiling point is slightly …

Web25. Why is the boiling point of alkane is higher compared to alkene and alkyne? between 10 and 20 degree celsius 26. what do you think will be the boiling point of the next alkane alkene and alkyne. Answer: The general expectation is that the boiling point of a hydrocarbon increases with the length of the carbon chain in the hydrocarbon. WebDec 20, 2024 · Whilst existing models have been successful in predicting boiling points for only a sub-class of alkanes, our model predicts boiling points for the full range of alkanes. … au から 格安sim デメリット
