Lewis structure

Draw the Lewis structure of adenosine triphosphate. 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), nitrogen (n_N, val = 5), oxygen (n_O, val = 6), and phosphorus (n_P, val = 5) atoms: 10 n_C, val + 16 n_H, val + 5 n_N, val + 13 n_O, val + 3 n_P, val = 174 Calculate the number of electrons needed to completely fill the valence shells for carbon (n_C, full = 8), hydrogen (n_H, full = 2), nitrogen (n_N, full = 8), oxygen (n_O, full = 8), and phosphorus (n_P, full = 8): 10 n_C, full + 16 n_H, full + 5 n_N, full + 13 n_O, full + 3 n_P, full = 280 Subtracting these two numbers shows that 280 - 174 = 106 bonding electrons are needed. Each bond has two electrons, so in addition to the 49 bonds already present in the diagram we expect to add 4 bonds. To minimize formal charge oxygen wants 2 bonds, nitrogen wants 3 bonds, and carbon wants 4 bonds. Identify the atoms that want additional bonds and the number of electrons remaining on each atom:  Add 4 bonds by pairing electrons between adjacent highlighted atoms. Additionally, atoms with large electronegativities can minimize their formal charge by forcing atoms with smaller electronegativities on period 3 or higher to expand their valence shells. The electronegativities of the atoms are 2.19 (phosphorus), 2.20 (hydrogen), 2.55 (carbon), 3.04 (nitrogen), and 3.44 (oxygen). Because the electronegativity of phosphorus is smaller than the electronegativity of oxygen, expand the valence shell of phosphorus to 5 bonds in 3 places. Therefore we add a total of 7 bonds to the diagram. Note that the six atom ring is aromatic, so that the single and double bonds may be rearranged: Answer: |   |
