WebThe reaction mechanism (or reaction path) provides details regarding the precise, step-by-step process by which a reaction occurs. The decomposition of ozone, for example, appears to follow a mechanism with two steps: O 3 ( g) O 2 ( g) + O O + O 3 ( g) 2 O 2 ( g) Each of the steps in a reaction mechanism is an elementary reaction. WebRobinson Schopf reaction can be compared to the things which differ from it. The comparison can distinguish its similarity and difference to the other things. Nothing can …
