The amount of resistance that a fuel has to detonation. The higher the number, the less likely it is that a particular fuel will detonate in a particular engine. The number is as compared to a standard fuel (not necessarily gasoline)
66. Octane is C8H18. therefore the total number of electrons is 6*8 + 18*1
Heptane has the number 0, and the number assigned to isooctane is 100. These two materials are used to grade the octane rating of petroleum fuels.This is called bracketing method.
The octane rating of gasoline is determined by conducting a test called the Research Octane Number (RON) test. This test measures the fuel's resistance to knocking or pinging in an engine. The higher the octane rating, the better the fuel is at resisting premature combustion, which can cause engine damage.
The molecular formula of octane is C8H18. It doesn't really have a "symbol."The "octane" in gasoline is actually "iso-octane" or 2,2,4-trimethylpentane. It has the same molecular formula, but the atoms are arranged differently than in n-octane.
Octane is saturated because it contains only single carbon-carbon bonds, meaning that each carbon atom is bonded to the maximum number of hydrogen atoms possible.
Octane has not special application excepting the so-called octane number.
93 octane works best.
Octane rating is the resistance to burning. For example (not real number) a gas with an octane rating of 50 will burn at 100 degrees Fahrenheit whereas a gas with an octane rating of 100 will burn at 200 degrees Fahrenheit. Higher the octane number the harder it is to burn.
n-heptane has a zero octane number because it is the reference fuel used to establish the octane rating scale. Its resistance to knocking is very poor, leading to a rating of zero on the scale. Other fuels are compared to n-heptane to determine their octane numbers.
100 octane. This is why aviation fuel (avgas) is typically called 100LL, which stands for 100 octane, low lead.
Research Octane Number 95
RON stands for Research Octane Number, which is a standard measure of a fuel's ability to resist knocking in a combustion engine. An octane rating of 95 RON indicates that the fuel has a higher resistance to knock compared to lower octane-rated fuels.
Methods of increasing the octane number of gasoline include blending it with higher-octane components such as ethanol or adding octane-boosting additives like tetraethyl lead or MTBE. Refining processes like catalytic cracking can also help to increase the octane number of gasoline by producing higher-octane hydrocarbons. Additionally, changing the fuel composition or utilizing advanced fuel injection systems in vehicles can help optimize the combustion of gasoline to improve octane performance.

The measure of antiknock properties in a fuel is typically expressed using the octane rating system. Higher octane ratings indicate better antiknock properties, meaning the fuel is less likely to cause knocking or pre-ignition in an engine.
The octane number is a measure of performance of a fuel. It is measured relative to pure isooctane which is given an arbitrary value of 100. It is possible for fuels to have an octane number higher than 100. The higher the octane number the more compression it takes for the fuel to detonate. Higher octane fuel is used usually in high performance vehicles where the engines have higher compression ratios. If the octane number of a fuel isn't high enough it can lead to engine knocking this is where the fuel detonates before the fuel is at its maximum compressive state in the engine, this can cause damage and lower performance.
