http://ursula.chem.yale.edu/~chem220/chem220js/STUDYAIDS/thermo/atomization.html The 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. The enthalpy change is temperature-dependent, and the bond … See more The term bond-dissociation energy is similar to the related notion of bond-dissociation enthalpy (or bond enthalpy), which is sometimes used interchangeably. However, some authors make the distinction that the … See more • Bond energy • Electronegativity • Ionization energy • Electron affinity • Lattice energy See more Bonds can be broken symmetrically or asymmetrically. The former is called homolysis and is the basis of the usual BDEs. Asymmetric scission of a bond is called heterolysis. For molecular hydrogen, the alternatives are: Symmetric: H2 → 2 … See more WebNov 9, 2024 · b Potential energy curves (PECs) of C 2 H 6 2+ dication as a function of C–C bond length by a rigid potential energy scan.
