Chemical Formula Description

The ETHANE molecule contains a total of 8 atom(s). There are 6 Hydrogen atom(s) and 2 Carbon atom(s). A chemical formula of ETHANE can therefore be written as:

C2H6

The chemical formula of ETHANE shown above is based on the molecular formula indicating the numbers of each type of atom in a molecule without structural information, which is different from the empirical formula which provides the numerical proportions of atoms of each type.

The above chemical formula is the basis of stoichiometry in chemical equations, i.e., the calculation of relative quantities of reactants and products in chemical reactions. The law of conservation of mass dictates that the quantity of each element given in the chemical formula does not change in a chemical reaction. Thus, each side of the chemical equation must represent the same quantity of any particular element based on the chemical formula.

Additional Information for Identifying ETHANE Molecule

  • Structure Data File (SDF/MOL File) of ETHANE

    The structure data file (SDF/MOL File) of ETHANE is available for download in the SDF page of ETHANE providing the information about the atoms, bonds, connectivity and coordinates of ETHANE, which is not completely available in the chemical formula representation. The ETHANE structure data file can be imported to most of the cheminformatics software for further analysis and visualization.

  • Chemical structure of ETHANE

    The chemical structure image of ETHANE is available in chemical structure page of ETHANE, which specifies the molecular geometry, i.e., the spatial arrangement of atoms in the chemical formula of ETHANE and the chemical bonds that hold the atoms together.

  • Molecular weight of ETHANE

    The molecular weight of ETHANE is available in molecular weight page of ETHANE, which is calculated as the sum of the atomic weights of each constituent element multiplied by the number of atoms of that element specified in the chemical formula of ETHANE.

  • InChI (IUPAC International Chemical Identifier) information of ETHANE

    The molecular chemical formulas lack structural information. An alternative textual expression including the structural information is InChI. The full standard InChI of ETHANE is:

    InChI=1S/C2H6/c1-2/h1-2H3

    It can provide a standard way to encode the molecular information of ETHANE to facilitate the search for the compound information in databases and on the web.

    The condensed, 27 character standard InChIKey (hashed version of the full standard InChI) of ETHANE is:

    InChIKey=OTMSDBZUPAUEDD-UHFFFAOYSA-N

    The InChIKey may allow easier web searches for ETHANE, but it needs to be linked to the full InChI to get back to the original structure of the ETHANE since the full standard InChI cannot be reconstructed from the InChIKey.
