The octane number of n-heptane is _.
Correct answer: A. 0
- A. 0
- B. 100
- C. 40
- D. 98
Explanation
If there is pure n-heptane, then its octane number is 0. n-heptane has zero octane number because of very poor knock resistance. If there is only pure iso-octane, then it's octane number is 100. The value of octane number for the mixture of n-heptane and iso-octane lies between zero to 100.
