Each relation below starts at this concept.
This is an authored directed relation from the source endpoint to the target endpoint.
Stepwise eliminations can share intermediates with substitution, while concerted eliminations do not contain a discrete intermediate.
The source supplies a substantive formal ingredient, dynamical sector, law, field content, or mechanism of the target theoretical framework.
wp-chem-organic-chemistryiupac-blue-bookpubchem-docsThis is an authored directed relation from the source endpoint to the target endpoint.
Intermediates are produced and consumed within mechanisms and require evidence distinguishing them from transition states and resting states.
The source is a material constituent, structural component, or underlying quantum field whose excitation realizes the target physical system or particle. The edge label and detail must distinguish composition from field excitation; neither implies a simple classical sum of parts.

Carbocations, ion pairs, radicals, or other intermediates may occur in stepwise substitutions but are absent from concerted pathways.
The source supplies a substantive formal ingredient, dynamical sector, law, field content, or mechanism of the target theoretical framework.
