Q:Hydrogen fluoride, HF, is a liquid at 15°C. All other hydrogen halides (represented by HX, where X is any other halogen) are gases at the same temperature. Why??
A:Fluorine has a very high electronegativity; therefore the H-F bond is stronger than any other H-X bond.;B:HF is smaller than any other H-X molecule; therefore it exhibits stronger London dispersion forces.;C:The dipoles in a HF molecule exhibit a particularly strong attraction force to the dipoles in other HF molecules.;D:The H-F bond is the most ionic in character compared to all other hydrogen halides.
