  2. Acetylene - Wikipedia

    en.wikipedia.org/wiki/Acetylene

    Acetylene (systematic name: ethyne) is the chemical compound with the formula C 2 H 2 and structure H−C≡C−H. It is a hydrocarbon and the simplest alkyne. [8] This colorless gas is widely used as a fuel and a chemical building block. It is unstable in its pure form and thus is usually handled as a solution. [9]

  3. Molecular orbital - Wikipedia

    en.wikipedia.org/wiki/Molecular_orbital

    As the two atoms become closer together, their atomic orbitals overlap to produce areas of high electron density, and, as a consequence, molecular orbitals are formed between the two atoms. The atoms are held together by the electrostatic attraction between the positively charged nuclei and the negatively charged electrons occupying bonding ...

  4. Ethylene - Wikipedia

    en.wikipedia.org/wiki/Ethylene

    Ethylene (IUPAC name: ethene) is a hydrocarbon which has the formula C 2 H 4 or H 2 C=CH 2.It is a colourless, flammable gas with a faint "sweet and musky" odour when pure. [7] It is the simplest alkene (a hydrocarbon with carbon–carbon double bonds).

  5. Alkyne - Wikipedia

    en.wikipedia.org/wiki/Alkyne

    A 3D model of ethyne (), the simplest alkyneIn organic chemistry, an alkyne is an unsaturated hydrocarbon containing at least one carbon—carbon triple bond. [1] The simplest acyclic alkynes with only one triple bond and no other functional groups form a homologous series with the general chemical formula C n H 2n−2.

    Cations and anions are also typically discrete and can be depicted unambiguously. For simple structures, say <10 atoms, it is helpful to depict all atoms explicitly. For more complex molecules, most hydrogen atoms attached to carbon are omitted, and carbon atoms are represented by vertices. For ease of readability, sans-serif fonts are ...

  7. Newman projection - Wikipedia

    en.wikipedia.org/wiki/Newman_projection

    3D structure A Newman projection is a drawing that helps visualize the 3-dimensional structure of a molecule. [ 1 ] This projection most commonly sights down a carbon-carbon bond, making it a very useful way to visualize the stereochemistry of alkanes.

    Huffman is the fourth most senior Democrat on the panel this Congress but would be No. 2 in seniority next year given two retirements; Stansbury would most likely be fifth next year.

  9. Linear molecular geometry - Wikipedia

    en.wikipedia.org/wiki/Linear_molecular_geometry

    The linear molecular geometry describes the geometry around a central atom bonded to two other atoms (or ligands) placed at a bond angle of 180°. Linear organic molecules , such as acetylene ( HC≡CH ), are often described by invoking sp orbital hybridization for their carbon centers.
