  2. Group 14 hydride - Wikipedia

    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. Lewis structure - Wikipedia

    en.wikipedia.org/wiki/Lewis_structure

    Expressing resonance when drawing Lewis structures may be done either by drawing each of the possible resonance forms and placing double-headed arrows between them or by using dashed lines to represent the partial bonds (although the latter is a good representation of the resonance hybrid which is not, formally speaking, a Lewis structure).

  4. 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 .

  5. Molecular orbital diagram - Wikipedia

    en.wikipedia.org/wiki/Molecular_orbital_diagram

    The next step in constructing an MO diagram is filling the newly formed molecular orbitals with electrons. Three general rules apply: The Aufbau principle states that orbitals are filled starting with the lowest energy; The Pauli exclusion principle states that the maximum number of electrons occupying an orbital is two, with opposite spins

    For example, sulfur hexafluoride (SF 6) is an octahedral molecule. Trigonal pyramidal : A trigonal pyramidal molecule has a pyramid-like shape with a triangular base. Unlike the linear and trigonal planar shapes but similar to the tetrahedral orientation, pyramidal shapes require three dimensions in order to fully separate the electrons.

  7. Dicarbon monoxide - Wikipedia

    en.wikipedia.org/wiki/Dicarbon_monoxide

    Dicarbon monoxide (C 2 O) is a molecule that contains two carbon atoms and one oxygen atom. It is a linear molecule that, because of its simplicity, is of interest in a variety of areas. It is, however, so extremely reactive that it is not encountered in everyday life.

  8. Quadruple bond - Wikipedia

    en.wikipedia.org/wiki/Quadruple_bond

    An example of a ditungsten compound with a quadruple bond is ditungsten tetra(hpp). Quadruple bonds between atoms of main-group elements are unknown. For the dicarbon (C 2 ) molecule as an example, molecular orbital theory shows that there are two sets of paired electrons in the sigma system (one bonding, one antibonding), and two sets of ...

  9. Diboron tetrafluoride - Wikipedia

    en.wikipedia.org/wiki/Diboron_tetrafluoride

    Structure and bonding [ edit ] Diboron tetrafluoride is a planar molecule with a B-B bond distance of 172 pm. [ 1 ] Although it is electron-deficient, the unsaturated boron centers are stabilized by pi-bonding with the terminal fluoride ligands.
