Well, clearly, there are 4 covalent bonds, and thus the number of shared electrons is #8#.


We look at the electronic structure of atomic carbon, hydrogen, and chlorine. Around the central carbon atom there are 4 valence electrons; these are shared with 2 hydrogens to form #2xxC-H# bonds, and with two chlorine atoms, to form #2xxCl# bonds.

Given this formal description, what is the geometry of the methylene chloride molecule?
