On a side note, it's interesting that octane is not the proper chemical term for the carbon chain. It's a pentane with 3 extra carbons and looks like this:




It's correct chemical name is 2,2,4 tri-methyl pentane. The 2/2/4 denote where the methyl groups are on the pentane chain. I suppose they call it octane because technically it still has 8 carbons, and octane rolls off the tongue better than 2,2,4 tri-methyl pentane.

I took organic chemistry too..congratulations on cracking this huge coverup by the gas companies.
