    en.wikipedia.org/wiki/Linkage_isomerism

    The complex cis-dichlorotetrakis(dimethylsulfoxide)ruthenium(II) (RuCl 2 (dmso) 4) exhibits linkage isomerism of dimethyl sulfoxide ligands due to S- vs. O-bonding. Trans -dichlorotetrakis(dimethylsulfoxide)ruthenium(II) does not exhibit linkage isomers.

  5. Chemical bond - Wikipedia

    en.wikipedia.org/wiki/Chemical_bond

    A chemical bond is the association of atoms or ions to form molecules, crystals, and other structures. The bond may result from the electrostatic force between oppositely charged ions as in ionic bonds or through the sharing of electrons as in covalent bonds, or some combination of these effects.

    en.wikipedia.org/wiki/Bonding_in_solids

    Covalent and ionic bonding form a continuum, with ionic character increasing with increasing difference in the electronegativity of the participating atoms. Covalent bonding corresponds to sharing of a pair of electrons between two atoms of essentially equal electronegativity (for example, C–C and C–H bonds in aliphatic hydrocarbons).

  8. Butyl group - Wikipedia

    en.wikipedia.org/wiki/Butyl_group

    In organic chemistry, butyl is a four-carbon alkyl radical or substituent group with general chemical formula −C 4 H 9, derived from either of the two isomers (n-butane and isobutane) of butane. The isomer n -butane can connect in two ways, giving rise to two "-butyl" groups:

  9. Molecular orbital theory - Wikipedia

    en.wikipedia.org/wiki/Molecular_orbital_theory

    Bond order is the number of chemical bonds between a pair of atoms. The bond order of a molecule can be calculated by subtracting the number of electrons in anti-bonding orbitals from the number of bonding orbitals, and the resulting number is then divided by two. A molecule is expected to be stable if it has bond order larger than zero.
