A detailed, step-by-step description of the sequence of bond-breaking and bond-forming events that occur during a chemical reaction. Mechanisms show the movement of electrons using curved arrows and include all intermediates and transition states along the reaction pathway.
Properties & Characteristics
A mechanism (reaction mechanism) is the step-by-step description of how a chemical reaction occurs at the molecular level, showing all bond-breaking and bond-forming events, intermediates, and transition states. A valid mechanism must: (1) add up to the overall balanced equation, (2) be consistent with the observed kinetics (rate law), and (3) be consistent with stereochemical observations. Mechanisms are supported (not proven) by experimental evidence.
Uses & Applications
Understanding reaction mechanisms is essential for: predicting products and selectivity, designing efficient synthetic routes, developing new catalysts, understanding drug metabolism, designing inhibitors (based on knowing the enzyme mechanism), and in forensic chemistry (determining reaction pathway of a chemical process).
Safety Information
Knowledge of mechanism allows prediction of hazardous by-products and intermediates that may not appear in the overall equation. In industrial chemistry, unexpected reactive intermediates (identified through mechanistic study) can cause explosions or toxic releases if not accounted for in process design.
