Reaction Intermediates

Postby Jose Torres » Wed Mar 06, 2019 10:03 pm

How do we figure out what are the reaction intermediates? For example, in question 7C.3:
Step 1 -
Step 2 -

How do we know that the intermediate is AB?

The reaction intermediate does not appear in the reactants or products of the overall reaction. It only appears in the intermediate steps.

Reaction intermediates appear and disappear within the course of the reaction, so they don't appear reactants on the first step or the products of the last step.

Another reason you can identify AB as an intermediate is because it is present in both of the reactions: As a product in the first reaction, and as a reactant in the second reaction.

AB would be an intermediate because if you sum up the elementary reactions for the overall reaction, AB is neither a product or reactant as it cancels out.
