    en.wikipedia.org/wiki/Group_14_hydride

    This series has the chemical formula X 2 H 6.Ethane is commonly found alongside methane in natural gas.The other hydrides of the chemical formula X 2 H 6 are less stable than the corresponding tetrahydrides XH 4, and they are more and more less stable as X goes from carbon (ethane C 2 H 6 is stable) down to lead (or flerovium) in the periodic table (diplumbane Pb 2 H 6 is unknown [1]).

  3. Diatomic carbon - Wikipedia

    en.wikipedia.org/wiki/Diatomic_carbon

    Diatomic carbon (systematically named dicarbon and 1λ 2,2λ 2-ethene), is a green, gaseous inorganic chemical with the chemical formula C=C (also written [C 2] or C 2). It is kinetically unstable at ambient temperature and pressure, being removed through autopolymerisation .

  4. Molecular geometry - Wikipedia

    en.wikipedia.org/wiki/Molecular_geometry

    A pure substance is composed of only one type of isomer of a molecule (all have the same geometrical structure). Structural isomers have the same chemical formula but different physical arrangements, often forming alternate molecular geometries with very different properties. The atoms are not bonded (connected) together in the same orders.

  5. Lewis structure - Wikipedia

    en.wikipedia.org/wiki/Lewis_structure

    In terms of Lewis structures, formal charge is used in the description, comparison, and assessment of likely topological and resonance structures [7] by determining the apparent electronic charge of each atom within, based upon its electron dot structure, assuming exclusive covalency or non-polar bonding.

  6. Chemical polarity - Wikipedia

    en.wikipedia.org/wiki/Chemical_polarity

    When comparing a polar and nonpolar molecule with similar molar masses, the polar molecule in general has a higher boiling point, because the dipole–dipole interaction between polar molecules results in stronger intermolecular attractions. One common form of polar interaction is the hydrogen bond, which is also

    Like diboron, dicarbon (C-C electron configuration:1σ g 2 1σ u 2 2σ g 2 2σ u 2 1π u 4) is a reactive gas-phase molecule. The molecule can be described as having two pi bonds but without a sigma bond. [18]

  9. Tetrahedral molecular geometry - Wikipedia

    en.wikipedia.org/wiki/Tetrahedral_molecular_geometry

    In a tetrahedral molecular geometry, a central atom is located at the center with four substituents that are located at the corners of a tetrahedron.The bond angles are arccos(− ⁠ 1 / 3 ⁠) = 109.4712206...° ≈ 109.5° when all four substituents are the same, as in methane (CH 4) [1] [2] as well as its heavier analogues.
