nounperfluoric acid (uncountable)
  1. uncountablechemistryThe perfluoric version of a simple oxyacid of fluorine: HFO₄, which either does not occur or occurs only in ways that are difficult for humans to detect.

    Since fluorine must always be negative relative to oxygen, oxyacids analogous to those of the other halogens cannot be expected (24). Almost certainly, perfluoric acid HFO₄, or fluoric acid HFO₃, or hypofluorous acid HOF, will not therefore be prepared.
