Well, it is not water, and it is not iron....

Explanation:

Organic substances feature the elements carbon, hydrogen, nitrogen, and oxygen, and a few other heteroatoms. If it ain't got carbon, then it ain't organic. Petroleum, a mixture of long chain hydrocarbons, i.e. #C_4H_10# to tars...fits under this umbrella.
