Fluorine bond enthalpy

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.

WebThe average bond energy is therefore +1662/4 kJ, which is +415.5 kJ per mole of bonds. That means that many bond enthalpies are actually quoted as mean (or average) bond enthalpies, although it might not actually say so. Mean bond enthalpies are sometimes referred to as "bond enthalpy terms". WebThe bond in F2 has a smaller bond dissociation enthalpy than the bond in Cl2. Which is the best explanation for this difference? (A) Fluorine is more electronegative than chlorine. (B) Lone pair-lone pair repulsions are stronger in F2 than in Cl2. (C) The F−F bond is longer than the Cl−Cl bond.
