The … WebMay 13, 2024 · 10.4: Bond Breaking and Bond Formation. The simplest and first process that takes place during a chemical transformation is the breaking of a bond. The following discussion is confined to covalent bonds because they are the most prevalent in organic molecules. Breaking bonds always requires an energy input.

WebJun 1, 2024 · If the amount of energy released when the new bonds are formed in the products is greater, then it is an exothermic reaction. If the amount of energy needed to break the bonds of the reactants is greater, then it is an endothermic reaction. One way to show this is using an energy diagram. Energy diagrams show the energy levels of … WebSep 12, 2024 · The energy required to break the O—H covalent bond (the bond dissociation energy) is about 111 kcal/mole, or in more proper SI units, 464 kJ/mole. The energy required to break an O—H••••O hydrogen bond is about 5 kcal/mole (21 kJ/mole), or less than 5% of the energy of a “real” covalent bond.
