Free rotation

  "id": "MLC-T-CHM-004657",
  "term": "Free rotation",
  "field": "Chemistry",
  "definition": "The unhindered rotation of one part of a molecule relative to another around a single bond. This occurs when the energy barrier to rotation is very low, allowing rapid interconversion between different conformations. Ethane exhibits free rotation around its carbon-carbon single bond at room temperature.",
