  2. Bond order - Wikipedia

    en.wikipedia.org/wiki/Bond_order

    The bond order between carbon and oxygen in carbon dioxide O=C=O is also 2. In phosgene O=CCl 2 , the bond order between carbon and oxygen is 2, and between carbon and chlorine is 1. In some molecules, bond orders can be 4 ( quadruple bond ), 5 ( quintuple bond ) or even 6 ( sextuple bond ).

  3. Superoxide - Wikipedia

    en.wikipedia.org/wiki/Superoxide

    In chemistry, a superoxide is a compound that contains the superoxide ion, which has the chemical formula O − 2. [1] The systematic name of the anion is dioxide(1−).The reactive oxygen ion superoxide is particularly important as the product of the one-electron reduction of dioxygen O 2, which occurs widely in nature. [2]

  4. Oxidation state - Wikipedia

    en.wikipedia.org/wiki/Oxidation_state

    The bond-order formula at the bottom is closest to the reality of four equivalent oxygens each having a total bond order of 2. That total includes the bond of order ⁠ 1 / 2 ⁠ to the implied cation and follows the 8 − N rule [7] requiring that the main-group atom's bond-order total equals 8 − N valence electrons of the neutral atom ...

  5. Oxygen - Wikipedia

    en.wikipedia.org/wiki/Oxygen

    The bond can be variously described based on level of theory, but is reasonably and simply described as a covalent double bond that results from the filling of molecular orbitals formed from the atomic orbitals of the individual oxygen atoms, the filling of which results in a bond order of two.

  6. Carbon–oxygen bond - Wikipedia

    en.wikipedia.org/wiki/Carbon–oxygen_bond

    A carbon–oxygen bond is a polar covalent bond between atoms of carbon and oxygen. [1] [2] [3]: 16–22 Carbon–oxygen bonds are found in many inorganic compounds such as carbon oxides and oxohalides, carbonates and metal carbonyls, [4] and in organic compounds such as alcohols, ethers, and carbonyl compounds.

  7. 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 ...

  8. Allotropes of oxygen - Wikipedia

    en.wikipedia.org/wiki/Allotropes_of_oxygen

    The ground state of O 2 has a bond length of 121 pm and a bond energy of 498 kJ/mol. [3] It is a colourless gas with a boiling point of −183 °C (90 K; −297 °F). [4] It can be condensed from air by cooling with liquid nitrogen, which has a boiling point of −196 °C (77 K; −321 °F).

  9. Triplet oxygen - Wikipedia

    en.wikipedia.org/wiki/Triplet_oxygen

    Under a molecular orbital theory framework, the oxygen-oxygen bond in triplet dioxygen is better described as one full σ bond plus two π half-bonds, each half-bond accounted for by two-center three-electron (2c-3e) bonding, to give a net bond order of two (1+2× ⁠ 1 / 2 ⁠), while also accounting for the spin state (S = 1).
