Carbynium ions

  "id": "MLC-T-CHM-001660",
  "term": "Carbynium ions",
  "field": "Chemistry",
  "definition": "The cationic species H2C.+ and its substitution derivatives, which result formally from protonating a carbyne or from ionizing a carbene by loss of one electron. The carbon atom is divalent, carries one nonbonding electron, and bears the positive charge, so these are radical cations. They differ from carbenium ions, R3C+, in which a trivalent carbon has a vacant p orbital and no unpaired electron.",
