Lewis structure
Draw the Lewis structure of trichlorofluoromethane. Start by drawing the overall structure of the molecule: Count the total valence electrons of the carbon (n_C, val = 4), chlorine (n_Cl, val = 7), and fluorine (n_F, val = 7) atoms: n_C, val + 3 n_Cl, val + n_F, val = 32 Calculate the number of electrons needed to completely fill the valence shells for carbon (n_C, full = 8), chlorine (n_Cl, full = 8), and fluorine (n_F, full = 8): n_C, full + 3 n_Cl, full + n_F, full = 40 Subtracting these two numbers shows that 40 - 32 = 8 bonding electrons are needed. Each bond has two electrons, so the above diagram has all the necessary bonds. There are 4 bonds and hence 8 bonding electrons in the diagram. Lastly, fill in the remaining unbonded electrons on each atom. In total, there remain 32 - 8 = 24 electrons left to draw: Answer: | |
