COMBUSTION AND OTHER OXIDATION-REDUCTION REACTIONS 39 C. Actually six of the carbons in n-octane have one integral oxidation number and the two end carbons have a different integral oxidation number. What are these oxidation numberst Hint: In determining the oxidation number of each carbon, assume that only the hydrogens surrounding each carbon determline the oxidation number for that carbon and that the oxidation numbers of the surrounding carbons have no effect In an automobile, a small amount of n-octane is incompletely oxidized in air, producing water and the toxic compound carbon monoxide. Write a balanced equation for this reaction, assuming that the only products are carbon monoxide and water. D. In an automobile, a catalytic converter helps the toxic carbon monoxide produced from the combustion of gasoline react with oxygen in the air to form non-toxic carbon dioxide. 4. A. Write a balanced equation for the reaction described above. B. What is the oxidation number of carbon in each of the following compounds? co Co,

Explanation / Answer

D)n-Octane is completely oxidized in air to CO & H2O

2 CH3-(CH2)6-CH3 + 17 O2 ------> 16 CO + 18 H2O

4.A) Balanced equation for the oxidation of gasoline

    2CO + O2 ------>2CO2

B)The Oxidation numbers of Carbon in the following:

   In CO , the oxidation number of carbon is 2+

In CO2   the oxidation number of carbon is   4+
