Tautomer - Wikipedia
Prototropy is the most common form of tautomerism and refers to the relocation of a hydrogen atom . Prototropic tautomerism may be considered a subset of acid-base behavior. Prototropic tautomers are sets of isomeric protonation states with the same empirical formula and total charge. en.wikipedia.org
