Octane number 2 2 4-trimethyl pentane is________________?
Correct answer: A. 100
- A. 100
- B. 90
- C. 80
- D. 70
Explanation
2,2,4-Trimethylpentane is iso-octane, the standard reference fuel assigned an octane number of 100. The likely distractor is 90, since ordinary gasoline may have an octane rating near that value, but it is not the value of the reference compound.
