Lewis structure

Draw the Lewis structure of D-tyrosine. 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), and oxygen (n_O, val = 6) atoms: 9 n_C, val + 11 n_H, val + n_N, val + 3 n_O, val = 70 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), and oxygen (n_O, full = 8): 9 n_C, full + 11 n_H, full + n_N, full + 3 n_O, full = 126 Subtracting these two numbers shows that 126 - 70 = 56 bonding electrons are needed. Each bond has two electrons, so in addition to the 24 bonds already present in the diagram add 4 bonds. To minimize formal charge carbon wants 4 bonds and oxygen wants 2 bonds. Identify the atoms that want additional bonds and the number of electrons remaining on each atom:  Fill in the 4 bonds by pairing electrons between adjacent highlighted atoms: Answer: |   |
