Question

hybridization of singlet and triplet carbene are

Answer 1

The term "carbene" may also refer to the specific compound H2C:, also called methylene, the parent hydride from which all other carbene compounds are formally derived.[1][2] Carbenes are classified as either singlets or triplets, depending upon their electronic structure. Most carbenes are very short lived, although persistent carbenes are known. One well-studied carbene is dichlorocarbene Cl2C:, which can be generated in situ from chloroform and a strong base.
