Jan 12, 2015 · The molecular shape of the C_2Cl_2 molecule is linear. Starting with its Lewis structure, the C_2Cl_2 molecule has a total of 22 valence electrons, 4 from each of the two carbon atoms and 7 from each of the two chlorine atoms. Thus, its Lewis structure must account for 22 valence electrons. So, the two carbon atoms are bonded to the two chlorine atoms through a single bond, and through a.
