Investigation of Organic Reactions and their Mechanisms will serve as a guide for the trained chemist who needs to characterise an organic chemical reaction and investigate its mechanism, but who is not an expert in physical organic chemistry.Such an investigation will lead to an understanding of which bonds are broken, which are made, and the order in which these processes happen.
