WebAug 31, 2024 · The H–F bond is more polar than H–O so is easier to break HF into H+ and F- than to break H2O into H+ and OH-. Hence HF is stronger acid than H2O. Why does HF have a low boiling point? Because there are fewer H-bonds to break, they have lower boiling points. WebAug 7, 2024 · The melting point of hydrogen fluoride is -83.6°C, as compared to that of ammonia, which is -77.73°C. How does this make any sense? Both hydrogen fluoride and ammonia show hydrogen bonding, which "elevates" the boiling points of these two compounds when compared to the rest of the pnictogen and halogen hydrides.
