Title: Minimum criteria a proposed mechanism should meet
1Minimum criteria a proposed mechanism should meet
- It must be consistent with all of the
experimental data. - It must make experimentally testable predictions
that, if not verified, would prove it false. - If several mechanisms are consistent with the
known data, prefrerence is given to the least
complicated one. - In any multistep mechanism, individual steps
should be unimolecular or bimolecular. - Each step in a mechanism should be energetically
favorable. - Each step in a mechanism should be chemically
reasonable. - Where possible, ad hoc additions to a mechanism
as devices to explain away inconsistencies with
experimental facts should be avoided.
