What do you mean by reaction mechanism? Give importance of reaction mechanism.

Answer»

i. Mechanism of an organic reaction is the complete step by step description of exactly which bonds break and which bonds form, in what manner and in what order to give the observed products.

ii. In general, reaction mechanism is a sequential account of:

  • the electron movement taking place during each step 
  • the bond cleavage and/or bond formation 
  • accompanying changes in energy and shapes of various species and 
  • rate of the overall reaction.

The individual steps, constitute the reaction mechanism.

iii. Importance of reaction mechanism: The knowledge of mechanism of a reaction is useful for understanding the reactivity of the concerned organic compounds and, in turn, helpful for planning synthetic strategies.
