WebC.S. Law, in Encyclopedia of Ocean Sciences (Second Edition), 2001 Methane (CH 4). CH 4 is the most abundant organic volatile in the atmosphere and, next to CO 2, is … 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-energy MO is the result of the overlap of the 2s orbital on carbon with the in-phase … Meer weergeven Methane is a chemical compound with the chemical formula CH4 (one carbon atom bonded to four hydrogen atoms).
