Lewis structure

Draw the Lewis structure of phenytoin. Start by drawing the overall structure of the molecule, ignoring potential double and triple bonds:  Count the total valence electrons of the carbon (n_C, val = 4), hydrogen (n_H, val = 1), nitrogen (n_N, val = 5), and oxygen (n_O, val = 6) atoms: 15 n_C, val + 12 n_H, val + 2 n_N, val + 2 n_O, val = 94 Calculate the number of electrons needed to completely fill the valence shells for carbon (n_C, full = 8), hydrogen (n_H, full = 2), nitrogen (n_N, full = 8), and oxygen (n_O, full = 8): 15 n_C, full + 12 n_H, full + 2 n_N, full + 2 n_O, full = 176 Subtracting these two numbers shows that 176 - 94 = 82 bonding electrons are needed. Each bond has two electrons, so in addition to the 33 bonds already present in the diagram add 8 bonds. To minimize formal charge oxygen wants 2 bonds and carbon wants 4 bonds. Identify the atoms that want additional bonds and the number of electrons remaining on each atom:  Fill in the 8 bonds by pairing electrons between adjacent highlighted atoms. Note that the six atom rings are aromatic, so that the single and double bonds may be rearranged: Answer: |   |
