  2. Carbon suboxide - Wikipedia

    en.wikipedia.org/wiki/Carbon_suboxide

    Carbon suboxide, or tricarbon dioxide, is an organic, oxygen-containing chemical compound with formula C 3 O 2 and structure O=C=C=C=O. Its four cumulative double bonds make it a cumulene . It is one of the stable members of the series of linear oxocarbons O=C n =O , which also includes carbon dioxide ( CO 2 ) and pentacarbon dioxide ( C 5 O 2 ).

  3. Triatomic molecule - Wikipedia

    en.wikipedia.org/wiki/Triatomic_molecule

    Ozone, O 3 is an example of a triatomic molecule with all atoms the same. Triatomic hydrogen, H 3, is unstable and breaks up spontaneously. H 3 +, the trihydrogen cation is stable by itself and is symmetric. 4 He 3, the helium trimer is only weakly bound by van der Waals force and is in an Efimov state. [1] Trisulfur (S 3) is analogous to ozone.

  4. Electron counting - Wikipedia

    en.wikipedia.org/wiki/Electron_counting

    ionic counting: H contributes 0 electrons (H +), C 4− contributes 2 electrons (per H), 0 + 1 × 2 = 2 valence electrons conclusion: Methane follows the octet-rule for carbon, and the duet rule for hydrogen, and hence is expected to be a stable molecule (as we see from daily life)

  5. 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.

  6. Lewis structure - Wikipedia

    en.wikipedia.org/wiki/Lewis_structure

    [1] [2] [3] Introduced by Gilbert N. Lewis in his 1916 article The Atom and the Molecule, a Lewis structure can be drawn for any covalently bonded molecule, as well as coordination compounds. [4] Lewis structures extend the concept of the electron dot diagram by adding lines between atoms to represent shared pairs in a chemical bond.

  7. Structural formula - Wikipedia

    en.wikipedia.org/wiki/Structural_formula

    Skeletal structural formula of Vitamin B 12.Many organic molecules are too complicated to be specified by a molecular formula.. The structural formula of a chemical compound is a graphic representation of the molecular structure (determined by structural chemistry methods), showing how the atoms are connected to one another. [1]

  8. Octet rule - Wikipedia

    en.wikipedia.org/wiki/Octet_rule

    The bonding in carbon dioxide (CO 2): all atoms are surrounded by 8 electrons, fulfilling the octet rule.. The octet rule is a chemical rule of thumb that reflects the theory that main-group elements tend to bond in such a way that each atom has eight electrons in its valence shell, giving it the same electronic configuration as a noble gas.

  9. Carbon trioxide - Wikipedia

    en.wikipedia.org/wiki/Carbon_trioxide

    The formation of CO 3 is inferred but it appears to decay spontaneously by the route 2 CO 32 CO 2 + O 2. with a lifetime much shorter than 1 minute. [3] Carbon trioxide can be made by blowing ozone at dry ice (solid CO 2), and it has also been detected in reactions between carbon monoxide (CO) and molecular oxygen (O 2).
