  2. 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 ).

  3. Ethane - Wikipedia

    en.wikipedia.org/wiki/Ethane

    The chief use of ethane is the production of ethylene (ethene) by steam cracking. Steam cracking of ethane is fairly selective for ethylene, while the steam cracking of heavier hydrocarbons yields a product mixture poorer in ethylene and richer in heavier alkenes (olefins), such as propene (propylene) and butadiene, and in aromatic hydrocarbons.

  4. Cracking (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Cracking_(chemistry)

    It is the principal industrial method for producing the lighter alkenes (or commonly olefins), including ethene (or ethylene) and propene (or propylene). Steam cracker units are facilities in which a feedstock such as naphtha, liquefied petroleum gas (LPG), ethane , propane or butane is thermally cracked through the use of steam in a bank of ...

  6. Vinyl group - Wikipedia

    en.wikipedia.org/wiki/Vinyl_group

    It is the ethylene (IUPAC name: ethene) molecule (H 2 C=CH 2) with one fewer hydrogen atom. The name is also used for any compound containing that group, namely R−CH=CH 2 where R is any other group of atoms. An industrially important example is vinyl chloride, precursor to PVC, [3] a plastic commonly known as vinyl.

  7. High-density polyethylene - Wikipedia

    en.wikipedia.org/wiki/High-density_polyethylene

    HDPE is known for its high strength-to-density ratio. [4] The density of HDPE ranges from 930 to 970 kg/m 3. [5] Although the density of HDPE is only marginally higher than that of low-density polyethylene, HDPE has little branching, giving it stronger intermolecular forces and tensile strength (38 MPa versus 21 MPa) than LDPE. [6]

  8. Alkene - Wikipedia

    en.wikipedia.org/wiki/Alkene

    For example, CH 3-CH 3 is the alkane ethANe. The name of CH 2 =CH 2 is therefore ethENe. For straight-chain alkenes with 4 or more carbon atoms, that name does not completely identify the compound. For those cases, and for branched acyclic alkenes, the following rules apply: Find the longest carbon chain in the molecule.

  9. Homologous series - Wikipedia

    en.wikipedia.org/wiki/Homologous_series

    The homologous series of straight-chained alkanes begins methane (CH 4), ethane (C 2 H 6), propane (C 3 H 8), butane (C 4 H 10), and pentane (C 5 H 12). In that series, successive members differ in mass by an extra methylene bridge (-CH 2 - unit) inserted in the chain. Thus the molecular mass of each member differs by 14 atomic mass units ...
