Lewis structure
Draw the Lewis structure of chrysene-d 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) and hydrogen (n_H, val = 1) atoms: 18 n_C, val + 12 n_H, val = 84 Calculate the number of electrons needed to completely fill the valence shells for carbon (n_C, full = 8) and hydrogen (n_H, full = 2): 18 n_C, full + 12 n_H, full = 168 Subtracting these two numbers shows that 168 - 84 = 84 bonding electrons are needed. Each bond has two electrons, so in addition to the 33 bonds already present in the diagram add 9 bonds. To minimize formal charge carbon wants 4 bonds. Identify the atoms that want additional bonds and the number of electrons remaining on each atom: Fill in the 9 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: | |
