Carbene - Wikipedia
Methylene is the simplest carbene. In organic 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 represents substituents or hydrogen atoms.

Carbene, any member of a class of highly reactive molecules containing divalent carbon atoms—that is, carbon atoms that utilize only two of the four bonds they are capable of forming with other atoms.
Carbene - Introduction, Singlet and Triplet Carbenes
A carbene is a divalent carbon atom with two electrons that are not shared with any other atoms. The carbene is called a singlet carbene when the two electrons have opposite spins, and a triplet carbene when they have parallel spins.
