Nitrene
In chemistry, a nitrene (R-N:) is the nitrogen analogue of a (carbon carbene). The nitrogen atom has only 6 electrons available and is therefore considered an electrophile. A nitrene is a reactive intermediate and is involved is many chemical reactions.
electron configuration
In the most simple nitrene linear imidogene (:N-H) two of the 6 available electrons form a covalent bond with hydrogen, two other create a free electron pair and the two remaining electrons occupy two degenerate p-orbitals. Consistent with Hund's rule the low energy form of imidogene is a triplet with one electron for each orbital and the high energy form is the singlet state with a electron pair in one filled orbital and one empty orbital
