Explanation of the combustion reaction of octane

A very important class of reactions is the combustion of hydrocarbons (compounds containing hydrogen and oxygen) to form CO2 and H2O. Let's look at the combustion of octane, which is the primary reaction in an automobile engine. ... Generally it can be described as C8H18+12.5O2=8CO2+9H2O as complete combustion.

The orbital shapes with more fluctuations with more highs, lows, and bends to its shape. it does contain more energy. So (another way to say it) when an electron transitions to a lower atomic energy level, its wave shape changes to have fewer kinks in it. But the electron doesn't leap anywhere
