Lewis structure

Draw the Lewis structure of chlorobutylidene fluorobenzene. 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), chlorine (n_Cl, val = 7), fluorine (n_F, val = 7), and hydrogen (n_H, val = 1) atoms: 10 n_C, val + n_Cl, val + n_F, val + 12 n_H, val = 66 Calculate the number of electrons needed to completely fill the valence shells for carbon (n_C, full = 8), chlorine (n_Cl, full = 8), fluorine (n_F, full = 8), and hydrogen (n_H, full = 2): 10 n_C, full + n_Cl, full + n_F, full + 12 n_H, full = 120 Subtracting these two numbers shows that 120 - 66 = 54 bonding electrons are needed. Each bond has two electrons, so in addition to the 24 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: Answer: |   |

Elemental oxidation states

The first step in finding the oxidation states (or oxidation numbers) in chlorobutylidene fluorobenzene is to draw the structure diagram. Next set every oxidation number equal to the atom's formal charge:  In chlorobutylidene fluorobenzene hydrogen is not bonded to a metal with lower electronegativity, so it will have an oxidation state of +1. Any element bonded to hydrogen gains the bonding electrons, decreasing their oxidation state by 1 for every bond:  With hydrogen out of the way, look at the remaining bonds. There are 1 carbon-chlorine bond, 1 carbon-fluorine bond, and 10 carbon-carbon bonds. For each of these bonds, assign the bonding electrons to the most electronegative element.  First examine the carbon-chlorine bond: element | electronegativity (Pauling scale) |  C | 2.55 |  Cl | 3.16 |   | |  Since chlorine is more electronegative than carbon, the electrons in this bond will go to chlorine. Decrease the oxidation number for chlorine (by 1 for single bonds, 2 for double bonds, and 3 for triple bonds), and increase the oxidation number for carbon accordingly:  Next look at the carbon-fluorine bond: element | electronegativity (Pauling scale) |  C | 2.55 |  F | 3.98 |   | |  Since fluorine is more electronegative than carbon, the electrons in this bond will go to fluorine:  Next look at the carbon-carbon bonds: element | electronegativity (Pauling scale) |  C | 2.55 |  C | 2.55 |   | |  Since these elements are the same the bonding electrons are shared equally, and there is no change to the oxidation states:  Now summarize the results: Answer: |   | oxidation state | element | count  -2 | C (carbon) | 2  -1 | C (carbon) | 6  | Cl (chlorine) | 1  | F (fluorine) | 1  0 | C (carbon) | 2  +1 | H (hydrogen) | 12
