acetic acid | structure diagram
Result
![Draw the Lewis structure of acetic 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: 2 n_C, val + 4 n_H, val + 2 n_O, val = 24 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): 2 n_C, full + 4 n_H, full + 2 n_O, full = 40 Subtracting these two numbers shows that 40 - 24 = 16 bonding electrons are needed. Each bond has two electrons, so in addition to the 7 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: | |](../image_source/5ca65c4c17080ee0af82ad8ba3c36e78.png)
