  "term": "Alkylidenes",
  "field": "Chemistry",
  "definition": "Carbenes of the form R2C: formed by replacing one or both hydrogens of methylene with alkyl groups, such as propylidene, CH3CH2CH:. The carbon is divalent with only six valence electrons, so these are short-lived reactive intermediates. They differ from alkylidene groups, the divalent substituents written =CR2, which attach to another atom through a double bond.",
