  2. Single bond - Wikipedia

    en.wikipedia.org/wiki/Single_bond

    Note depiction of the single bond. Lewis structure for methane. Note depiction of the four single bonds between the carbon and hydrogen atoms. Lewis structure for an alkane . Note that all the bonds are single covalent bonds. In chemistry, a single bond is a chemical bond between two atoms involving two valence electrons.

  3. Carbon–carbon bond - Wikipedia

    en.wikipedia.org/wiki/Carbon–carbon_bond

    The carbon–carbon single bond is a sigma bond and is formed between one hybridized orbital from each of the carbon atoms. In ethane, the orbitals are sp 3-hybridized orbitals, but single bonds formed between carbon atoms with other hybridizations do occur (e.g. sp 2 to sp 2). In fact, the carbon atoms in the single bond need not be of the ...

  4. Lewis structure - Wikipedia

    en.wikipedia.org/wiki/Lewis_structure

    Initially, one line (representing a single bond) is drawn between each pair of connected atoms. Each bond consists of a pair of electrons, so if t is the total number of electrons to be placed and n is the number of single bonds just drawn, t−2n electrons remain to be placed. These are temporarily drawn as dots, one per electron, to a maximum ...

  5. Covalent bond - Wikipedia

    en.wikipedia.org/wiki/Covalent_bond

    The bond between the nitrogen and each oxygen is a double bond in one structure and a single bond in the other two, so that the average bond order for each N–O interaction is ⁠ 2 + 1 + 1 / 3 ⁠ = ⁠ 4 / 3 ⁠. [8]

  6. Chemical bond - Wikipedia

    en.wikipedia.org/wiki/Chemical_bond

    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. A polar covalent bond is a covalent bond with a significant ionic character. This means that the two shared electrons are closer to one of the atoms than the other ...

  7. Carbon–hydrogen bond - Wikipedia

    en.wikipedia.org/wiki/Carbon–hydrogen_bond

    This bond is a covalent, single bond, meaning that carbon shares its outer valence electrons with up to four hydrogens. This completes both of their outer shells, making them stable. [2] Carbon–hydrogen bonds have a bond length of about 1.09 Å (1.09 × 10 −10 m) and a bond energy of about 413 kJ/mol (see table below).

    Fructose, with a bond at the hydroxyl (OH) group upper left of image with unknown or unspecified stereochemistry. Wavy single bonds represent unknown or unspecified stereochemistry or a mixture of isomers. For example, the adjacent diagram shows the fructose molecule with a wavy bond to the HOCH 2 - group at the left. In this case the two ...

  9. Molecular orbital diagram - Wikipedia

    en.wikipedia.org/wiki/Molecular_orbital_diagram

    MO diagram of dihydrogen Bond breaking in MO diagram. The smallest molecule, hydrogen gas exists as dihydrogen (H-H) with a single covalent bond between two hydrogen atoms. As each hydrogen atom has a single 1s atomic orbital for its electron, the bond forms by overlap of these two atomic orbitals. In the figure the two atomic orbitals are ...
