    Methane - Wikipedia

    • Methane is a chemical compound with the chemical formula CH4 (one carbon atom bonded to four hydrogen atoms). It is a group-14 hydride, the simplest alkane, and the main constituent of natural gas. The abundance of methane on Earth makes it an economically attractive fuel, although capturing and storing it is difficult because it is a gas at standard temperature an… 展开

    Properties and bonding

    Methane is a tetrahedral molecule with four equivalent C–H bonds. Its electronic structure is described by four bonding molecular orbitals (MOs) resulting from the overlap of the valence orbitals on C and H. The lowest-ener… 展开

    How does methane affect the environment?
    Increased concentrations of methane in the atmosphere contribute to the greenhouse effect, whereby greenhouse gases (particularly carbon dioxide, methane, and water vapour) absorb infrared radiation (net heat energy) and reradiate it back to Earth ’s surface, potentially trapping heat and producing substantial changes in climate.

      What are the dangers of methane?
      Methane is not toxic by any route. The immediate health hazard is that it may cause thermal burns. It is flammable and may form mixtures with air that are flammable or explosive. Methane is violently reactive with oxidizers, halogens, and some halogen compounds. Methane is an asphyxiant and may displace oxygen in a workplace atmosphere.
