Characteristics of reaction intermediates

 

Reaction intermediates (or intermediates/reactive intermediates) are molecules that are produced in the process of chemical reactions with short existence time, high energy, and high reactivity. When the reaction occurs, it will quickly transform into a more stable molecule, which can be separated and stored only under special circumstances, such as low temperature.

 

Reaction intermediate is an important link in the research of organic reaction process

Intermediates in chemical reactions can generally quickly become reaction products. Reaction intermediates are generally not easy to separate and test at room temperature, but their existence can be inferred through research methods such as kinetics. Some can be separated and tested under special experimental conditions. The presence of intermediates can help explain how some chemical reactions proceed. Most chemical reactions are multi-steps, that is, the reaction will not be completed at one time, and the reaction intermediates have high energy and are unstable, and it is easy to react and become a product.

 

Types of reaction intermediates

 

In organic chemistry, common reaction intermediates include carbocations, carbanions, free radicals, carbenes, and azenes.
