Carbene | Reactive Intermediate |

by
  • Neutral bivalent species.
  • six electrons in outermost shell.
  • 4 – are bonded and 2 are non bonded electrons.
  • homolytic cleavage.
  • have tendency to accept a pair of electron.
  • Types 1. Singlet 2. Triplet
  1. Singlet Carbene
  • sp2 hybridized.
  • angular shape.
  • 2 non bonded electron present.
  • opposite spin.

2. Triplet Carbene

  • Sp Hybridized
  • linear shape.
  • 2 non bonded electron present.
  • same spin present.
Triplet carbene is more stable than singlet Carbene due to less repulsion between two non-bonded electrons which are present in two different orbitals.
