Key Concepts

Reaction Mechanism

A reaction mechanism details the sequence of elementary steps that a complex reaction follows. It breaks down the overall process into individual stages, revealing how reactants transform into products step by step, often providing insight into the kinetics and the pathway by which bonds are broken and formed.

Reaction Intermediates

Intermediates are transient species that form in one step of the reaction mechanism and are consumed in a subsequent step. They do not appear in the overall balanced equation because they are neither present at the start nor at the end of the reaction, yet they play a critical role in connecting different stages of the mechanism.

Net Reaction

The net reaction is the overall transformation obtained by combining all the individual steps of the mechanism and canceling out the intermediates. It represents the total stoichiometric change from the initial reactants to the final products, summarizing the essential chemical change that has occurred.
