  "id": "MLC-T-CHM-008032",
  "term": "non-Kekulé structure",
  "field": "Chemistry",
  "definition": "A species whose unpaired electrons make it impossible to draw any Lewis structure in which every bonding electron is paired up in a single or double bond. Trimethylenemethane and m-xylylene are examples, and in each, any Kekulé drawing leaves at least two conjugated atoms without a pi-bond partner.",
