# What do oxidation reduction reactions do?

Feb 4, 2018

Well for one, drive the economy....

#### Explanation:

Our civilization relies on the combustion of fossil fuels....for instance take the hexanes that we put in our motors...

${C}_{6} {H}_{14} \left(l\right) + \frac{19}{2} {O}_{2} \left(g\right) \rightarrow 6 C {O}_{2} \left(g\right) + 7 {H}_{2} O \left(l\right) + \Delta$

And although this is unusual and not part of the regular syllabus we could assign oxidation numbers to the carbons in hexanes...

${H}_{3} C - C {H}_{2} C {H}_{2} C {H}_{2} C {H}_{2} C {H}_{3}$...the terminal carbons are $C \left(- I I I\right)$, and the central carbon is $C \left(- I I\right)$...and all these carbons are oxidized to $C \left(+ I V\right)$...you could write a redox equation in an electron transfer process...dioxygen, as above, is the species that is reduced...
