While gasoline relies on carbon-hydrogen bonds for energy, nitromethane leverages the oxygen atoms within its nitro group to support a more violent and efficient burn. It is composed of a single carbon atom bonded to three hydrogen atoms and a nitro group (NO₂).

This nitro group is the source of both its incredible energy density and its unique behavior inside an engine. For this reason, fuels used in Top Fuel dragsters are often described as having an "octane rating" of 120 or higher; nitromethane allows these engines to operate on the edge of what is physically possible without tearing themselves apart.
Nitromethane, conversely, is a simple and potent chemical compound with the formula CH₃NO₂. Standard gasoline is a complex mixture of various hydrocarbons, primarily composed of chains of carbon and hydrogen atoms.

This number quantifies the fuel's resistance to "knocking" or "pinging"—uncontrolled premature explosions within the engine's cylinders. Crucially, it burns so cleanly and controllably that it does not exhibit the detonation characteristics that gasoline does, even in the most extreme compression ratios.
