Lewis structure
Draw the Lewis structure of norflurane. Start by drawing the overall structure of the molecule: Count the total valence electrons of the carbon (n_C, val = 4), fluorine (n_F, val = 7), and hydrogen (n_H, val = 1) atoms: 2 n_C, val + 4 n_F, val + 2 n_H, val = 38 Calculate the number of electrons needed to completely fill the valence shells for carbon (n_C, full = 8), fluorine (n_F, full = 8), and hydrogen (n_H, full = 2): 2 n_C, full + 4 n_F, full + 2 n_H, full = 52 Subtracting these two numbers shows that 52 - 38 = 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 38 - 14 = 24 electrons left to draw: Answer: | |
