Chemical Formula Description

The methane molecule contains a total of 5 atom(s). There are 4 Hydrogen atom(s) and 1 Carbon atom(s). A chemical formula of methane can therefore be written as:

CH4

The chemical formula of methane 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 Methane Molecule

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

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

  • Chemical structure of methane

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

  • Molecular weight of methane

    The molecular weight of methane is available in molecular weight page of methane, 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 methane.


  • InChI (IUPAC International Chemical Identifier) information of methane

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

    InChI=1S/CH4/h1H4

    It can provide a standard way to encode the molecular information of methane 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 methane is:

    InChIKey=VNWKTOKETHGBQD-UHFFFAOYSA-N

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