Nonclassical carbocation

{
  "id": "MLC-T-CHM-008008",
  "term": "Nonclassical carbocation",
  "field": "Chemistry",
  "definition": "A carbocation in which the positive charge is delocalized over more than three atoms through a three-center, two-electron bond. This delocalization results in a structure that cannot be adequately represented by conventional Lewis structures with localized bonds. The norbornyl cation is a well-known example of a nonclassical carbocation.",
