It may seem counterintuitive to say that HF is the weakest hydrohalic acid because fluorine has the highest electronegativity. However, the H-F bond is very strong; if the H-X bond is strong, the resulting acid is weak. A strong bond is determined by a short bond length and a large bond dissociation energy.

WebJan 3, 2024 · The bond is labeled as "the strongest in organic chemistry," because fluorine forms the strongest single bond to carbon.
