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 ... One Page Lesson: Determining Electron-Group & Molecular Geometry The repulsive forces between bonding and non-bonding electrons determine the three-dimensional geometry of the “groups” of electrons around a central atom. Because the negative charges repel one another, the electron groups arrange themselves so they are as far apart as possible Molecular hydrogen (H2) or diatomic hydrogen is a tasteless, odorless, flammable gas. a & b only e.
