  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 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.

  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). In a skeletal formula, a double bond ...

  4. 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 .

  5. Bond length - Wikipedia

    en.wikipedia.org/wiki/Bond_length

    It is generally considered the average length for a carboncarbon 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. Double bond rule - Wikipedia

    en.wikipedia.org/wiki/Double_bond_rule

    In chemistry, the double bond rule states that elements with a ... Double bonds for carbon and nearest neighbours ... (n=2) C carbon (n=2) N nitrogen (n=2) O oxygen ...

  7. Chemical bond - Wikipedia

    en.wikipedia.org/wiki/Chemical_bond

    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] Molecules that are formed primarily from non-polar covalent bonds are often immiscible in water or other polar solvents, but much more soluble in non-polar solvents such as hexane.

  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. Diatomic molecule - Wikipedia

    en.wikipedia.org/wiki/Diatomic_molecule

    All diatomic molecules are linear and characterized by a single parameter which is the bond length or distance between the two atoms. Diatomic nitrogen has a triple bond, diatomic oxygen has a double bond, and diatomic hydrogen, fluorine, chlorine, iodine, and bromine all have single bonds. [6]
