Octane is a colorless liquid with a gasoline-like smell. It has a melting point of −57.1 to −56.6 °C; −70.9 to −69.8 °F and boiling point of 125.1 to 126.1 °C; 257.1 to 258.9 °F. Its refractive index is 1.398. Its density is lesser than water and very much insoluble in water. Octane is a component of gasoline (petrol). Octane is also volatile and very flammable like all other low-molecular-weight hydrocarbons.
The related term with octane is octane rating or octane number. We define it as a standard measure of the performance of an engine or aviation fuel. So fuels with a higher octane rating are useful in high-performance gasoline engines that require higher compression ratios.
Among its isomeres, the isooctane (2,2,4-trimethyl pentane) is most important, because its octane rating is 100. So it is an important constituent of petrol. Octane was found in the crude oil discovered by Edwin L. Drake in August 1859. He was the first to drill for oil. The octane rating was developed in 1927 by Graham Edgar.
The chemical formula of octane is
When we burn octane in air, chemical reaction with oxygen gas
Combustion reactions are the rapid reactions that produce the flame. A gas with a lower octane number ignites at lower temperatures and is as such more flammable. Higher octane number gas requires more compression and higher temperatures to burn efficiently.
Octane prevents the air-fuel mixture from igniting before the spark plug does it. The sparking or firing of the air-fuel mixture at the proper time gives you the maximum power an engine is designed for. Using gasoline of a higher octane number than your engine is designed is only a wastage of your money.
Q.1.What is the molar mass of Octane?
Ans- Molar mass of
The atomic mass of hydrogen is 1.00794
The atomic mass of carbon is 12.0107
No of atoms of hydrogen is 18
Molecular weight calculation:
Q.2. What is the octane booster?
Ans- An octane booster protects against low octane level issues by increasing the octane rating, and it improves performance by helping to ensure that fuel in a cylinder ignites exactly when it should, even in the high-compression engine.
