Lewis structure
Draw the Lewis structure of 1, 2, 3, 4-tetraphenylnaphthalene. 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: 34 n_C, val + 24 n_H, val = 160 Calculate the number of electrons needed to completely fill the valence shells for carbon (n_C, full = 8) and hydrogen (n_H, full = 2): 34 n_C, full + 24 n_H, full = 320 Subtracting these two numbers shows that 320 - 160 = 160 bonding electrons are needed. Each bond has two electrons, so in addition to the 63 bonds already present in the diagram add 17 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 17 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: | |
