Lewis structure
![Draw the Lewis structure of 1, 2-propanediol dibenzoate. 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), and oxygen (n_O, val = 6) atoms: 17 n_C, val + 16 n_H, val + 4 n_O, val = 108 Calculate the number of electrons needed to completely fill the valence shells for carbon (n_C, full = 8), hydrogen (n_H, full = 2), and oxygen (n_O, full = 8): 17 n_C, full + 16 n_H, full + 4 n_O, full = 200 Subtracting these two numbers shows that 200 - 108 = 92 bonding electrons are needed. Each bond has two electrons, so in addition to the 38 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: | |](../image_source/4bc1d376315de5e6a3400defd1756ea3.png)
