Lewis structure
Draw the Lewis structure of acetonitrile-1-13 C. 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 nitrogen (n_N, val = 5) atoms: 2 n_C, val + 3 n_H, val + n_N, val = 16 Calculate the number of electrons needed to completely fill the valence shells for carbon (n_C, full = 8), hydrogen (n_H, full = 2), and nitrogen (n_N, full = 8): 2 n_C, full + 3 n_H, full + n_N, full = 30 Subtracting these two numbers shows that 30 - 16 = 14 bonding electrons are needed. Each bond has two electrons, so in addition to the 5 bonds already present in the diagram add 2 bonds. To minimize formal charge 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: Fill in the 2 bonds by pairing electrons between adjacent highlighted atoms: Answer: | |
