### 15.71

How do you know H2O is not an intermediate, considering how it is not in the first step of the reaction?

H2O cannot be an intermediate because it is one of the reactants in the overall reaction.

Yes, I know, but overall reaction was not given. Considering how you fomulate the overall reaction based on the steps, how would you then know that H2O is not an intermediate when it is in the second step? For example my overall reaction based on the steps involved was RCN + 2OH- -> RCONH2 + OH-, since I thought H2O was an intermediate.
