Presentation Transcript

    1. Minimum 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.
