This is an authored directed relation from the source endpoint to the target endpoint.
Nucleophilicity is a kinetic reactive role related to, but not identical with, Lewis basicity as a thermodynamic donor concept.
The target is a model, idealization, restricted ansatz, approximation scheme, phenomenological fit, or historical representation used for the source system or theory. It need not have a universal small error parameter and is not thereby a controlled limit or effective theory. The edge label and detail must identify the precise status.

Nucleophilic substitution joins electron-pair donation to departure or displacement at an electrophilic center through a mechanism such as or .
The source field, particle, charge, current, or interaction couples to, acts on, binds, forms, or stabilizes the target in the stated regime. The edge label and detail must identify the exact coupling, interaction, or binding claim and its qualifications.
