Answer» Explanation: In chemistry, a carbene is a molecule containing a neutral carbon atom with a valence of two and two unshared valence electrons. The general formula is R-(C:)-R' or R=C: where the R represent substituents or hydrogen atoms. 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 [3] are known. One well-studied carbene is dichlorocarbene Cl2C:, which can be generated in situ from chloroform and a strong base.ó |
