WebAug 21, 2024 · The bond enthalpy of the H-F bond. Because the fluorine atom is so small, the bond enthalpy (bond energy) of the hydrogen-fluorine bond is very high. The chart below gives values for all the hydrogen-halogen bond enthalpies: bond enthalpy (kJ mol-1) H-F +562: H-Cl +431: H-Br +366: H-I +299: WebApr 2, 2024 · Fluorine is the most electronegative element and the Lewis structure of HF shows one H– F bond and three lone pairs. Fluorine attracts electrons very strongly—even the ones in the H– F bond so that the fluorine atom ends up with more than its fair share of electrons and the hydrogen atom ends up with less.
