ABSTRACT

In the following example, all of the bond changes occur simultaneously or the events cannot be distinguished; it is thus considered one step:

2. Multistep reactions must involve: a. More than one bonding change during the complete reac-

tion, and b. Have bond-making and bond-breaking events which are not

simultaneous and can be distinguished from each other. Example: More than one step is detected for the following reaction:

Cl and CH3 are intermediates in this mechanism, generated in a previous step and consumed in a subsequent step. They are actually detected by instruments and analytical reactions.
