  "id": "MLC-T-CHM-012102",
  "term": "Tolyl ion",
  "field": "Chemistry",
  "definition": "A carbocation with the chemical formula C7H7+, derived from toluene by the formal removal of a hydride ion. This ion exists as three structural isomers: ortho-tolyl, meta-tolyl, and para-tolyl, corresponding to the position of the positive charge on the benzene ring relative to the methyl group. The tolyl ion is a distinct species from the more stable tropylium ion, which is a common fragment in the mass spectra of toluene and related compounds.",
