I'm pretty sure most synthetic rubber compounds, including neoprene, are derived from hydrocarbons. Their chemical formulas contain a lot of "C"s and "H"s.
I can't say either way if neoprene reacts with aluminum. The corrosion that takes place where rubber is in contact with an aluminum tank may just be crevice corrosion. If it were galvanic, I would think the whole tank would act as an anode.
