  "id": "MLC-T-CHM-011830",
  "term": "Tautomerism",
  "field": "Chemistry",
  "definition": "A type of structural isomerism where two or more interconvertible compounds, called tautomers, exist in dynamic equilibrium. This interconversion typically involves the migration of a hydrogen atom or proton and the rearrangement of single and double bonds. Keto-enol tautomerism is a common example, where a ketone or aldehyde is in equilibrium with its enol form.",
