Herein we comparatively comment on the molecular metric ‘amidicity’, a descriptor of amide reactivity, and differing methods to determining it; with focus on lactam-rings. Specifically, our established amidicity percentage (AM%) approach is quantitatively contrasted with the transamidation (TA) method. This comment is organised into two sections, firstly addressing the differing methods in context of the computational bases of amidicity. This is followed by the quantitative demonstration that although both the AM% and H-RS methods provide estimates of resonance enthalpy (Delta H-RE), the former is more reliable across a wider set of systems. The robustness of the AM% approach is affirmed by quantitative matching of experimental NMR and kinetics measurements tracking changes in amide reactivities, including in Penicillin arising from modulation of its amide group and environmental effects.
