This is also an example of a central atom containing non-bonding valence electron pairs. If such pairs are present, then they are included in the Lewis structure for the molecule, which describes the arrangement of all bonding and non-bonding valence electrons. Answer and Explanation: The ...
Click the Symmetry Operations above to view them in 3D Methane contains 4 equivalent C3axes and 3 equivalent C2axes. The C2axes contain 3 equivalent S4axes. There are 6 equivalent σvplanes. Hence methane belongs to the Tdgroup. A four-fold axis of improper rotation S4in the CH4molecule. ...
