Vedclass · Answer

(B) The octane number is a measure of the anti-knocking property of a fuel. By definition,$n$-heptane is assigned an octane number of $0$ because it has very poor anti-knocking properties and causes significant knocking in engines. Iso-octane ($2,2,4$-trimethylpentane) is assigned an octane number of $100$. Since $n$-heptane has the lowest defined octane number among standard reference fuels,it is the correct answer.

Which of the following has the lowest octane number?
