In the real world, you have to regard the distance and the actual charge difference and distribution.. In the case of HF and HI, fluorine has the highest electronegativity, which means the bond in HF is more polarised than in HI.
Web26 de nov. de 2024 · Re: Polarity and Boiling Point. Since a higher polarity means the atom/molecule has a stronger negatively charged end and a stronger positively charged end, this leads to greater dipole-dipole interactions between atoms/molecules. Thus, it's harder to pull apart the atoms or molecules and requires a higher boiling point. Web1 de abr. de 2016 · Gas Chromatography Theory. The separation of compounds is based on the different strengths of interaction of the compounds with the stationary phase (“like-dissolves-like”-rule). The stronger the interaction is, the longer the compound interacts with the stationary phase, and the more time it takes to migrate through the column (=longer ...
