  2. Carbon–nitrogen bond - Wikipedia

    en.wikipedia.org/wiki/Carbonnitrogen_bond

    A carbonnitrogen bond is a covalent bond between carbon and nitrogen and is one of the most abundant bonds in organic chemistry and biochemistry. [1]Nitrogen has five valence electrons and in simple amines it is trivalent, with the two remaining electrons forming a lone pair.

  3. Double bond - Wikipedia

    en.wikipedia.org/wiki/Double_bond

    Double bonds occur most commonly between two carbon atoms, for example in alkenes. Many double bonds exist between two different elements: for example, in a carbonyl group between a carbon atom and an oxygen atom. Other common double bonds are found in azo compounds (N=N), imines (C=N), and sulfoxides (S=O).

  4. Imine - Wikipedia

    en.wikipedia.org/wiki/Imine

    In organic chemistry, an imine (/ ɪ ˈ m iː n / or / ˈ ɪ m ɪ n /) is a functional group or organic compound containing a carbonnitrogen double bond (C=N). The nitrogen atom can be attached to a hydrogen or an organic group (R). The carbon atom has two additional single bonds. [1] [2] Imines are common in synthetic and naturally ...

  5. Chemical bond - Wikipedia

    en.wikipedia.org/wiki/Chemical_bond

    In non-polar covalent bonds, the electronegativity difference between the bonded atoms is small, typically 0 to 0.3. Bonds within most organic compounds are described as covalent. The figure shows methane (CH 4), in which each hydrogen forms a covalent bond with the carbon. See sigma bonds and pi bonds for LCAO descriptions of such bonding. [22]

  6. Valence (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Valence_(chemistry)

    Double bonds are considered to be two bonds, triple bonds to be three, quadruple bonds to be four, quintuple bonds to be five and sextuple bonds to be six. In most compounds, the valence of hydrogen is 1, of oxygen is 2, of nitrogen is 3, and of carbon is 4.

  7. Bond order - Wikipedia

    en.wikipedia.org/wiki/Bond_order

    In carbon monoxide, − C≡O +, the bond order between carbon and oxygen is 3. In thiazyl trifluoride N≡SF 3, the bond order between sulfur and nitrogen is 3, and between sulfur and fluorine is 1. In diatomic oxygen O=O the bond order is 2 (double bond). In ethylene H 2 C=CH 2 the bond order between the two carbon atoms is also 2. The bond ...

  9. Molecular orbital diagram - Wikipedia

    en.wikipedia.org/wiki/Molecular_orbital_diagram

    The σ from the 2p is more non-bonding due to mixing, and same with the 2s σ. This also causes a large jump in energy in the 2p σ* orbital. The bond order of diatomic nitrogen is three, and it is a diamagnetic molecule. [12] The bond order for dinitrogen (1σ g 2 1σ u 2 2σ g 2 2σ u 2 1π u 4 3σ g 2) is three because two electrons are now ...
