Definition
A high bond dissociation energy (BDE) is a measure of the strength of a chemical bond between two atoms. It is defined as the energy required to break a bond between two atoms, typically measured in kilojoules per mole (kJ/mol). A high BDE indicates that the bond is difficult to break, and a low BDE indicates that the bond is more easily broken.
Etymology
The term “dissociation energy” was first coined in the late 19th century by the German chemist Friedrich August Kekulé. The term “bond dissociation energy” was introduced in the mid-20th century to describe the energy required to break a chemical bond.
Additional Information
Bond dissociation energy is an important concept in chemistry, as it plays a crucial role in understanding the chemical properties of molecules. It is used to predict the stability of molecules, evaluate the reactivity of functional groups, and design new materials with specific properties. In addition, BDE is a key factor in determining the performance of fuels, lubricants, and other energy-related systems. A high BDE is often associated with strong chemical bonds, which are difficult to break. This means that the molecules are more stable and less reactive. For example, the carbon-carbon double bond in ethene has a high BDE, which makes it difficult to break. In contrast, a low BDE is often associated with weak chemical bonds, which are easily broken. This means that the molecules are more reactive and can undergo chemical reactions more readily. The measurement of BDE is typically carried out using experimental techniques such as photoelectron spectroscopy or thermal dissociation methods. The resulting values are then used to understand the chemical properties of the molecule and to predict its behavior in different environments.
Usage Notes
Bond dissociation energy is a technical term that is typically used in academic or industrial settings. It is rarely used in everyday conversation, but it is important for chemists and materials scientists to understand the concept in order to design and optimize new materials and systems.
