What is the Hammond postulate and its implications for transition state structure?

Bond energy is the energy required to separate two bonded atoms, which is the vertical distance from the minimum in the curve to zero on the graph, 436 kJ/mol. Apr 3, 2025 ... When a bond is strong, there is a higher bond energy because it takes more energy to break a strong bond. This correlates with bond order and bond length. The bond enthalpy tells you how much heat energy is needed to break one mole of the bond. That is bound to need energy and so bond enthalpies are always ... Table of bond dissociation energies. 9.
