Lewis structure
Draw the Lewis structure of nylon 12. 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: 12 n_C, val + 23 n_H, val + n_N, val + n_O, val = 82 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): 12 n_C, full + 23 n_H, full + n_N, full + n_O, full = 158 Subtracting these two numbers shows that 158 - 82 = 76 bonding electrons are needed. Each bond has two electrons, so in addition to the 37 bonds already present in the diagram add 1 bond. 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 1 bond by pairing electrons between adjacent highlighted atoms: Answer: | |
