n-heptane

iso-octane

2-methyl octane

3-methyl octane

Detailed explanation-1: -n-heptane is defined as the zero point of the octane rating scale. 2, 2, 4-Trimethylpentane has an octane rating of 100, whereas n-heptane has an octane rating of 0. The octane number is based on an arbitrary scale which is a measure of its ability to resist knocking, as it burns on combustion.
Detailed explanation-2: -It is a scale from zero to 100. Basically octane number is defined for the mixture of n-heptane and iso-octane in terms of volume of iso-octane present in the mixture. If there is pure n-heptane then its octane number is 0.
Detailed explanation-3: -Octane number of n-Heptane is 0. Was this answer helpful?
Detailed explanation-4: -The higher the octane number, the better is the fuel and the greater is the performance (in general). n-heptane is assigned a value of 0, meaning it is a terrible choice for a gasoline engine!
