Draw an appropriate Lewis structure for {eq}CH_4 {/eq} and predict its shape. Molecular Geometry: If a covalent compound has three or more atoms in its representative molecule, then this molecule will adopt a certain geometry (shape). In VSEPR theory, this geometry minimizes the repuls...
CH4 is a simple molecule consisting of one carbon atom bonded to four hydrogen atoms. It is a nonpolar molecule with a tetrahedral shape. The carbon-hydrogen bonds in CH4 are covalent bonds, which are relatively strong. However, the intermolecular forces between CH4 molecules are weak London dis...

We study the adsorption of three gases – CH4, CO2 and SF6 –in the crystal of a porous organic cage (POC) molecule, CC3-R, whose structural flexibility is known by experiment to play an important role in adsorption of large guest molecules [L. Chen, P. S. Reiss, S. Y. Chong, D...

Eads also equals sum of the binding energy (Eb, characterizing the interaction between a single isolated gas molecule with the shale surface) and adsorbate stabilization energy (Einter-ad) which accounts for intermolecular interactions between the gas molecules (Bocquet et al., 2005)(3)Eads=Eb+...

Furthermore, based on the frontier molecular orbital theory, it was concluded that the electrons density would be transferred from the HOMO of the CH4 or NO molecule to the LUMO of the [InO]+ or [InOH]2+ group due to their lower energy gaps. The energy levels of both the HOMO and ...
