What is the name of the hydrocarbon shown in the picture?

Answer explanation

Octane is one of the few chemical names that is part of everyday life and is recognized by the public. When you stop at a garage to fill up your car, you usually see the octane rating of the fuel displayed on the pump, 95 or 97, but what does it mean? The higher the octane number, the more compression required for fuel ignition. Fuels with high octane numbers are used in high performance gasoline engines. Fuels with low octane number (or high cetane numbers) are used in diesel engines, where fuel is not compressed.
