Lewis structure
Draw the Lewis structure of 2, 4-dimethylthiazole. 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 sulfur (n_S, val = 6) atoms: 5 n_C, val + 7 n_H, val + n_N, val + n_S, val = 38 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 sulfur (n_S, full = 8): 5 n_C, full + 7 n_H, full + n_N, full + n_S, full = 70 Subtracting these two numbers shows that 70 - 38 = 32 bonding electrons are needed. Each bond has two electrons, so in addition to the 14 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: | |
