Lewis structure
![Draw the Lewis structure of chlorodifluoromethane. 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), fluorine (n_F, val = 7), and hydrogen (n_H, val = 1) atoms: n_C, val + n_Cl, val + 2 n_F, val + n_H, val = 26 Calculate the number of electrons needed to completely fill the valence shells for carbon (n_C, full = 8), chlorine (n_Cl, full = 8), fluorine (n_F, full = 8), and hydrogen (n_H, full = 2): n_C, full + n_Cl, full + 2 n_F, full + n_H, full = 34 Subtracting these two numbers shows that 34 - 26 = 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 26 - 8 = 18 electrons left to draw: Answer: | |](../image_source/c34b342e7de639eecb38c6fcc26414f9.png)
