Keto-enol tautomer framework: K_T = exp(-ΔG/RT); x_enol = K_T/(1 + K_T)

Layer 2 — Chemistryin the heterocyclic-chemistry subtree

The keto-enol tautomer equilibrium framework — the archetypal proton-migration isomerisation between an sp²-carbonyl + α-CH form (keto) and a sp²-α-carbon + enol-OH form (enol), mediated by α-C-H bond-breaking and O-H bond-forming in…
