  2. 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 carbon–nitrogen 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.

  3. Carbon–nitrogen bond - Wikipedia

    en.wikipedia.org/wiki/Carbonnitrogen_bond

    Similar to carbon–carbon bonds, these bonds can form stable double bonds, as in imines; and triple bonds, such as nitriles. Bond lengths range from 147.9 pm for simple amines to 147.5 pm for C-N= compounds such as nitromethane to 135.2 pm for partial double bonds in pyridine to 115.8 pm for triple bonds as in nitriles.

  4. Double bond - Wikipedia

    en.wikipedia.org/wiki/Double_bond

    In chemistry, a double bond is a covalent bond between two atoms involving four bonding electrons as opposed to two in a single 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 ...

  5. Bond length - Wikipedia

    en.wikipedia.org/wiki/Bond_length

    It is generally considered the average length for a carbon–carbon single bond, but is also the largest bond length that exists for ordinary carbon covalent bonds. Since one atomic unit of length (i.e., a Bohr radius) is 52.9177 pm, the C–C bond length is 2.91 atomic units, or approximately three Bohr radii long.

  6. Covalent radius - Wikipedia

    en.wikipedia.org/wiki/Covalent_radius

    Rotational spectroscopy can also give extremely accurate values of bond lengths. For homonuclear A–A bonds, Linus Pauling took the covalent radius to be half the single-bond length in the element, e.g. R(H–H, in H 2) = 74.14 pm so r cov (H) = 37.07 pm: in practice, it is usual to obtain an average value from a variety of covalent compounds ...

  7. Carbon monoxide - Wikipedia

    en.wikipedia.org/wiki/Carbon_monoxide

    The carbon and oxygen are connected by a triple bond that consists of a net two pi bonds and one sigma bond. The bond length between the carbon atom and the oxygen atom is 112.8 pm . [ 11 ] [ 12 ] This bond length is consistent with a triple bond, as in molecular nitrogen (N 2 ), which has a similar bond length (109.76 pm) and nearly the same ...

  8. 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. Carbon–carbon bond - Wikipedia

    en.wikipedia.org/wiki/Carboncarbon_bond

    In fact, the carbon atoms in the single bond need not be of the same hybridization. Carbon atoms can also form double bonds in compounds called alkenes or triple bonds in compounds called alkynes. A double bond is formed with an sp 2-hybridized orbital and a p-orbital that is not involved in the hybridization. A triple bond is formed with an sp ...
