Lewis structure
Draw the Lewis structure of hexachloroethane. Start by drawing the overall structure of the molecule: Count the total valence electrons of the carbon (n_C, val = 4) and chlorine (n_Cl, val = 7) atoms: 2 n_C, val + 6 n_Cl, val = 50 Calculate the number of electrons needed to completely fill the valence shells for carbon (n_C, full = 8) and chlorine (n_Cl, full = 8): 2 n_C, full + 6 n_Cl, full = 64 Subtracting these two numbers shows that 64 - 50 = 14 bonding electrons are needed. Each bond has two electrons, so the above diagram has all the necessary bonds. There are 7 bonds and hence 14 bonding electrons in the diagram. Lastly, fill in the remaining unbonded electrons on each atom. In total, there remain 50 - 14 = 36 electrons left to draw: Answer: | |
