Lewis structure
![Draw the Lewis structure of erythorbic acid. 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: 6 n_C, val + 8 n_H, val + 6 n_O, val = 68 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): 6 n_C, full + 8 n_H, full + 6 n_O, full = 112 Subtracting these two numbers shows that 112 - 68 = 44 bonding electrons are needed. Each bond has two electrons, so in addition to the 20 bonds already present in the diagram add 2 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 2 bonds by pairing electrons between adjacent highlighted atoms: Answer: | |](../image_source/d997d493906c9b1f8fe94a8c9686af45.png)
