Lewis structure
Draw the Lewis structure of 1, 4-bis(trifluoromethyl)benzene-13 C6. 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), fluorine (n_F, val = 7), and hydrogen (n_H, val = 1) atoms: 8 n_C, val + 6 n_F, val + 4 n_H, val = 78 Calculate the number of electrons needed to completely fill the valence shells for carbon (n_C, full = 8), fluorine (n_F, full = 8), and hydrogen (n_H, full = 2): 8 n_C, full + 6 n_F, full + 4 n_H, full = 120 Subtracting these two numbers shows that 120 - 78 = 42 bonding electrons are needed. Each bond has two electrons, so in addition to the 18 bonds already present in the diagram add 3 bonds. To minimize formal charge carbon wants 4 bonds. Identify the atoms that want additional bonds and the number of electrons remaining on each atom: Fill in the 3 bonds by pairing electrons between adjacent highlighted atoms. Note that the six atom ring is aromatic, so that the single and double bonds may be rearranged: Answer: | |
