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 bond-dissociation energy ( BDE, D0, or DH°) is one measure of the strength of a chemical bond A−B. It can be defined as the standard enthalpy change when A−B is cleaved by homolysis to give fragments A and B, which are usually radical species. inail click day 2021

Bond Dissociation Enthalpy - Definition and Detailed Explanation …

WebApr 11, 2024 · An oxygen-hydrogen bond has a bond enthalpy of 463 kJ/mol, for a total of 926 kJ/mol to break apart water. The only other bond I've found for hydrogen that's stronger is the fluorine-hydrogen bond, with 567 kJ/mol. It's a bit more complicated for oxygen, as oxygen can form both double and triple bonds, whereas hydrogen is limited to single bonds. 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".
