Greater imfa results in higher melting points

WebJul 17, 2024 · The stronger the intermolecular forces, the more is the boiling point of substances. This is due to an increase in the enthalpy of vaporization. Why does the higher the molecular mass the stronger the intermolecular force we have? Because higher molecular mass corresponds to a greater number of electrons. This means increased … WebMelting and Boiling Points of the Halogens Table 10.1 The increase in melting and boiling points with increasing atomic/molecular size may be rationalized by considering how the strength of dispersion forces is affected by the electronic structure of the atoms or molecules in the substance.

Why the melting and boiling point of helium is lower than …

WebThe general relationship between IMF and melting point is that the stronger the intermolecular force, the higher the melting point. For example, a non-polar compound such as Br 2 that only has London dispersion forces tend to have a low melting point because only a very small amount of energy is required to break its molecules apart. On … WebWhen a substance is melted, IMFAs break greater IMFA=higher melting point (harder to break molecules) Volatility vs. IMFA volatility=tendency to evaporate (more … css 上移一层 https://colonialbapt.org
